STM RELEASE 8.1 HAS ARRIVED
.... 2 More Real Goodies .....
With the RELEASE 8.1 of our DYNATUNE-XL STM Module we have implemented TWO small but important new features which have been requested by our growing User Community:
1) The First New Feature has been requested by primarily the Racing Community by those who are running (Non-Linear) Rocker Suspensions & High Aerodynamic Loads. DyNATUNE-XL STM can now simulate Non-Linear Wheel Force Deflection Curves combined with or without
Non-Linear Motion Ratio's of the Spring Damper Unit. In order to realize this new feature the overall numerical complexity of the simulation machine had to be increased significantly.

2) The Second New Feature has been requested by the OEM User Community, where typically one has to deal with Rubber Top Mounts to which the Damper Units are attached (primarily for Ride Comfort and Plushness) and as such basically coupling a Damper and a Spring in Series effectively creating a Mechanical High Pass Filter.
Thanks to a massive update in the differential equations for such a complex Frequency Dependent System, the User Community can now exactly define the Minimal Top Mount Stiffness, which would be required for best compromise between Comfort Perception and Body/Wheel Control.

Words From THE TEAM:
With the arrival of DYNATUNE-XL SUSPENSION TUNING MODULE RELEASE 8.1, we have closed the RELEASE 8.1 Development Loop for the DYNATUNE-XL Tool Suite.
By adding 2 important new Features:
the DYNATUNE-XL Suspension Tuning Module was given internally a massive simulation upgrade. Though one could think that the implementation of solely these 2 new Features was easy, anyone who is familiar with simulating Non-Linear Systems and the Complexity of Solving the Differential Equations for "Spring / Damper in Series Systems" will appreciate the programming efforts and more importantly the Ultimate Performance of the Tool.
By implementing these final 2 Goodies, all "Ride" relevant systems are now properly represented in the DYNATUNE-XL Suspension Tuning Module. Further development of the Tire Model would be possible but would equally blow the scope of the this Tool.
I am sure that the DYNATUNE-XL Suspension Tuning Module is a one-of-a-kind tool without comparison on the market. With this upgrade the tool will be well prepared for the upcoming years. I hope you do all appreciate it even more !
Best Regards & Thank You for Your Continuing Enthusiasm for DYNATUNE-XL !

R&H RELEASE 8.1 HAS ARRIVED - RACE & EXPERT
.... the Icing on the Cake ....
With the RELEASE 8.1 of our DYNATUNE-XL R&H Module TWO long desired Features have been implemented to make the tool complete, a more detailed Steering System and Limited Slip Differential Representation in the Model.
|
STEERING SYSTEM:
We have added several new Parameters for the Steering System, shown on the right:
|
|
These additional parameters can be extracted from the Kinematic Analysis in the Suspension Design Module:
- Ackermann Percentage which will allow more detailed Tire Slip Angle calculations.
- Caster Trail, King Pin Offset & Scrub Radius Data will allow to calculate accurately Steering Wheel Torque Feedback both under Lateral Forces as well as under Combined Lateral and (a-symmetric) Longitudinal Forces.
Pure Lateral Force - NO LSD
|
Combined Lateral & Longitudinal Force with Front LSD
|
LIMITED SLIP DIFFERENTIAL DRIVE-LINE SYSTEM:
Now the effects of Limited Slip Differentials for Front and Rear Axle with Traction / Overrun and Torque Preload Settings be simulated in great detail.
|
The effects of applying a-symmetric Left & Right Longitudinal Forces are fully considered in the resulting Yaw Moment of the Vehicle. Not only for Traction but also for Braking.
Optionally it is possible to activate Ideal L/R Brake or Traction Force Distribution simulating Full Torque Vectoring. The consequences of this Yaw Moment on the Under / Oversteer Balance have been fully integrated into the 7-DOF Full Vehicle & Tire Model. |
|
It is worth noting that RELEASE 8.1 is now also "EV Proof". It is now possible to activate regenerative braking in combination with hydraulic braking using the correct suspension Anti-Angles and correct Brake Power Distribution into the respective EV Powertrain resp. Hydraulic Brake System.
Words From THE TEAM:
With the arrival of DYNATUNE-XL RIDE & HANDLING MODULE RELEASE 8.1, we have closed the full development loop of the R&H Module by adding 2 important Features:
Although one could think that the implementation of solely these new Features was easy, anyone who is familiar with simulating Limited Slip Differentials does know that they are complex. As such, here the implementation of LSD did require some important modifications to the 7-DOF Vehicle Model & Tire Model, the latter also partially driven by the updated and enhanced Steering System Representation.
By implementing these final 2 Features all relevant systems are now properly represented for Vehicle Dynamic Analysis.
In order to make the R&H Module EV proof we have also implemented the possibility to integrate Regenerative & Combined Hydraulic Braking and FULL Torque Vectoring in Traction/Braking which is of particular interest for the many multi motor EV's that are coming onto the market.
I am sure that the R&H Module is now well prepared for the upcoming years. I hope you do all appreciate "The Icing on The Cake".

SDM RELEASE 8.1 EXPERT HAS ARRIVED
.... with ONE Fantastic New Exiting Feature ....
Upon many request DYNATUNE-XL has developed for the SUSPENSION DESIGN MODULE in the "Expert" Version a truly Unique Optimizer for Kinematic and Elasto-Kinematic Suspension Characteristics, allowing the user in a quasi full automatic mode - in a matter of minutes - to create the best possible Suspension Geometry and most suitable Link Stiffness (Bushing) Values for his selection of Constraints & Targets.
Based on a "Sensitivity Study" for each X-, Y-, & Z-Coordinate and Stiffness in the Suspension System, the Optimization procedure will focus on minimizing the Difference between Actual Performance and Target Performance by a propietary DYNATUNE-XL Cost Function, The Suspension Performance Index.
A great Bonus of the "Sensitivity Study" comes for the User who can see in the Blink-of-an-Eye which Coordinates affect a specific Suspension Characteristic the most.
|
The User can fully control the Constraints for the Optimization Exercise. Each Coordinate of the Suspension Link Joints can be on-request (De-) Activated (to consider for example important packaging constraints). The Design Space / Operating Range for the Optimization Process (entirely executed with the standard MS EXCEL SOLVER ADD-IN) can be entirely customized to the requirements of the User. |
|
Words From THE TEAM:
Ever after the Introduction of the hugely successful Damper Optimization Tool in RELEASE 8.0.1 of the DYNATUNE-XL SUSPENSION TUNING MODULE we had always looked on how to create a similar feature for the DYNATUNE-XL SUSPENSION DESIGN MODULE.
With the arrival of DYNATUNE-XL SUSPENSION DESIGN MODULE RELEASE 8.1, we have implemented and realized this long term wish and created the Holy Grail of Suspension Engineering: Automatically design Suspension Geometry and Elasto-Kinematic Characteristics to pre-defined targets.
The feedback we received during Beta Testing of the Software was excellent. All Users did truly love the optimizer and some superb results have been realized on the road already.
Including the MS Excel Solver Add-In turned out to be a great but also challenging decision. Setting Up the optimization procedure AND setting all the constraints for it correctly, took quite a bit more effort and "lateral" thinking than anticipated. But at the end, the hard work did pay off and we made it work.
I have no doubt that the Kinematic & Elasto-Kinematic Optimization Tool is at the State of the Art Frontier of Suspension Design. It is truly unique to have such a "click on a button" optimizer for such complex systems as Suspensions available. I am sure that SDM will keep for many more years to come a top - if not the top - position in desktop Suspension Analysis Tools.
I hope you like what you see and share my enthusiasm for this Release.

DYNATUNE SUSPENSION TUNING MODULE RELEASE 8.0.1
The Suspension Tuning Module has received some very major enhancements in RELEASE 8.0.1 making it even more efficient and more valuable as a Superb Tuning Tool for Spring & Damper Setup.
The 4-Poster Frequency Domain Sweep can now be executed with a "Constant Input Velocity Signal" allowing to address specific damper speeds. On top of that this signal does allow to post-process to some degree very non-linear damper curves more accurately and is therefore not only limited to creating an averaged damping value for the analysis.

On top of that this signal does allow to post-process to some degree very non-linear damper curves more accurately and is therefore not only limited to creating an averaged damping value for the analysis.
The Frequency Response Sweep does provide a whole range of additional results & KPI, all aimed at describing the ride performance more accurately. Dynamic Percentages of Critical Damping, Dynamic Tire Contact Patch Loads and Dissipated Energies in Tire and Dampers are a few to mention.
The Time Domain Ride "Step" Function has been joined by a Havsin ("Half Sine") Function allowing to investigate more accurately "Kerb-Stone-Like" Events. On top of that the Tire Model can now "loose" contact with the ground and hence can simulate Dynamic Contact Patch Load Fluctuations more accurately.
Instead of running many manual iterations towards an optimized damper setting, STM does now allow to run a Fully Automatic Loop creating in a First Step a Suitable Damper Curve - for the selected test events - and in a Second Step the Optimized Overall, Bump & Rebound Damping Rates. The User can - if desired - define Start Damping Values for this Process.
DYNATUNE R&H MODULE RELEASE 8.0 "EXPERT" & "RACE" VERSION
Being the first of all DYNATUNE-XL Tools, the R&H tool has received also some significant upgrades. It is fair to say that almost all of the calculation procedures have been entirely re-written for performance improvements, both from a physical as numerical perspective. There are a lot of new features and improvements of which the most important are:
The Main New Feature is a largely revised "Enhanced Tire Model" and a new worksheet dedicated solely to the Tire Models. The Tire Models are no longer integrated in the "CHASSIS DATA" Worksheet but do now live in their own "TIRE DATA" Worksheet.
The Main New Feature is a largely revised "Enhanced Tire Model" and a new worksheet dedicated solely to the Tire Models. The Tire Models are no longer integrated in the "CHASSIS DATA" Worksheet but do now live in their own "TIRE DATA" Worksheet.
- Tire Grip / Friction Coefficient has become a Load Dependent Parameter which will truly allow the User to "Create your Own Tire". Making Tire Grip Load Dependent has had major consequences on all calculations and has added significant coherence to the results..
- The Enhanced Tire Model does provide the 4 instantaneous Tire Operating Points in the 7-DOF Vehicle Model.
- Many Tire Plotting Features have been added.
A small, but very useful feature is Front & Rear Ride Height Adjustment. On the request of many users this feature has been implement and any change in Ride Height will affect CoG-Height & Roll Center Height as actually happening in real life.
The 7-DOF Handling Model does now provide ulterior information on the effects of Suspension Compliance on Tire Forces and does show the Tire Operating Points on the Tire Map. This does allow the User to immediately identify which axle is limiting car performance performance and by how much.

Further to many other detailed improvements R&H RELEASE 8.0 does provide a very convenient "Laptime Sensitivity Study" allowing the User to a run a Study, which of the typical track-side tuning parameters does provide the most gain in Laptime for the given track. Up to 20 Parameters can be set.
As the R&H EXPERT Version has always been slightly biassed towards the typical OEM Vision of Vehicle Dynamics Development, the EXPERT 8.0 Release has therefore seen some major enhancements in the Frequency Steer & Step Steer Procedures. Several added automatic procedures do now allow to cover the whole Velocity Range in "One Go" providing to the Expert Vehicle Dynamicist a "One Blink of An Eye" Overview for Stability and Transient Response. The "RACE" Version does not have these features as it has been optimized primarily for Laptime Simulation.
DYNATUNE SDM MODULE RELEASE 8.0 "RACE" & "EXPERT" VERSION
As the Suspension Design Module has been fully up to date for Suspension Kinematics, the focus for Improvements has been on details and Load Case Analysis Enhancements.
Both "RACE" & "EXPERT" Version do now allow to attach the Push-Rod / Spring Damper Unit to the Upright/Knuckle for analyzing Combined Jounce & Steering Motions and investigate the effect on Ride Height changes for these particular suspension configurations.
The "EXPERT" Version comes with an major update to the "Vehicle Loadcase Generation" Tool and a new automatic procedure to create out of these Vehicle Load Cases 12 Suspension Link Load Cases. A basic "R&H-Type" Vehicle Model does allow to create Vehicle Corner Loads which in a secondary step are being transformed into Suspension Link Loads. Dynamic Load Factors can be considered.
A very helpful tool to check Link Loads and Suspension Compliance's in an early Concept Stage or a useful guideline for the Club Racer who is into modifying his own vehicle.

DYNATUNE DRIVE-LINE DESIGN MODULE RELEASE 8.0
The Drive-Line Design Module comes in RELEASE 8.0 with 2 Major Enhancements:
- The Tool has been "Electrified" allowing to simulate a typical E-Drive Powertrain with a fixed Ratio.
- Rotational Inertia's of the Drive Line (ICE/MGU, Clutch & Gearbox) and Wheels can now be fully considered.
DYNATUNE BRAKE-SYSTEM DESIGN MODULE RELEASE 8.0
The Brake-System Design Module comes in RELEASE 8.0 also with 2 Major Enhancements:
- Algorithms in the Tool have been upgraded to deal with a "Classic" OEM-Type Tandem Brake Master Cilinder.
- High Downforce & High Drag Vehicle characteristics have been implemented in Braking Performance Analysis.
Words From THE TEAM:
With the arrival of DYNATUNE RELEASE 8.0 many of the desired "Missing" Features of RELEASE 7.1 have now been implemented and I must admit that it feels like running into the Finish Line after a 24h Race in the rain.
Upgrading the various tools to become compatible with MS Excel 2013 & Upwards has been an enormous task, which did require to look into all calculation routines, often forced re-writing them completely and sometimes succeeded only due to finding a solution for an insolvable software gimmick with pure luck. The final change to compiling the workbooks into executable files paves the way for many more years of DYNATUNE distribution and compatability with future versions of MS Excel.
It is a bit sad to say goodbye to the "LIGHT", "BASE" & "PRO" Versions but as 99% of the Customers are solely interested in the "EXPERT" and "RACE" Versions, the effort of updating them too was not justified.
All major improvements have been described above. Next to those there are many minor improvements all focused on improving the quality of results and maximizing User Comfort. Each Workbook does have a new README section and on each worksheet page are now direct links to the corresponding DYNATUNE FAQ page which will make the learning of the tools for new user hopefully a lot easier. Wherever needed, buttons are placed to jump from one section to the other section quickly. Calculation Routines come with additional Pop-Up Information Windows where needed.
At the end, the hard work did pay off. The tools have been thoroughly revised and enhanced in many areas with lots of little new details. The Tools have been modernized and are more efficient than before. More licensing options can be made available to satisfy particular customer and business needs. DYNATUNE is ready for the upcoming decade !
I hope you like what you see.

Words From THE TEAM:
With the arrival of these 3 latest additional Software Variants for DYNATUNE 7.1 and the 3 exiting standalone tools BDM, DDM & STM the Product Portfolio of the Software has closed a 360° development loop.
Both the RIDE & HANDLING Tool as the SUSPENSION DESIGN MODULE are available in "BASE", "PRO", "RACE" and "EXPERT" Version, each with specific tools and features that are tailor made for the intended customers and their skill level.
Adding the concept of "Link Stiffness" into the "PRO" and "EXPERT" Suspension Design Module allows to investigate what effects (bushing-) stiffness has on suspension deformation, changing kinematic suspension characteristics by load application at the wheel. Furthermore the possibility of looking into specific (combined) load cases provides an excellent tool to effectively analyze and design a GEOMETRY, COMPLIANCE & LOAD CHARACTERISTICS of a suspension system without having to revert to hugely complex and costly multi-body-systems analysis tools.
Adding the "RACE" Variant in the DYNATUNE RIDE & HANDLING will help typical racing customers to focus on those tests that are of their primary interest without needing to understand all the extra information of the more scientific tests that are available in the "EXPERT" Version. Eliminating some of those tests has improved - in the spirit of racing - the CPU time, making Performance Envelope & Lap Time calculation up to 20% faster and more efficient.
The 3 standalone tools for longitudinal dynamics and in-detail suspension tuning have filled in the gaps that many clients were asking for. I hope that all of them do help you make your cars go better & faster !
Best Regards & Thank you for your continuing enthusiasm for the tools !

Words From THE TEAM:
DYNATUNE 7.0 represents with the "EXPERT" Level a state of the art vehicle dynamics tool in EXCEL ® that provides an ALL-IN-ONE solution to the customer for doing a complete investigation of the Ride & Handling Characteristics of his vehicle. Through adding in the "PRO" & "EXPERT" Level the PERFORMANCE ENVELOPES feature, DYNATUNE 7.0 provides in the "EXPERT" Version with LAPTIME SIMULATION now several state of the art tools to make trade-off studies even more detailed and complete. Not only Objective Test Procedures can be used as judging criteria, but also comparisons on a real test/race track can now be taken into consideration for judging the final quality of the vehicle setup. For each point on the track the state of the vehicle can be analyzed. If wanted, any objective metrics can be calculated for any data point on the test-track.
Adding additional USER TOOLS will make especially the life of "novices" a lot easier. For many of the suspension and tire data now exists a reference database which will allow to select from commonly used references number the correct value for your parameter.
All of these features remain true to the original concept of being "only as complex as necessary" and must strictly remain applicable in the familiar MS EXCEL ® environment, permitting the customer to concentrate on dynamics and not on learning how to to drive the software.
The "EXPERT" Level has also demonstrated to have arrived at the boundaries of the capabilities of MS EXCEL ®. Due to the complexity of various algorithms and the amount of data to be handled an i5/i7 multi-core processor (or similar) is highly recommended for those who plan to run frequent laptime simulations.
