DYNATUNE-XL LIGHT VERSION
The APP you always wanted ....
|
|
The DYNATUNE-XL R&H "LIGHT" MODULE stands as the historical foundation of the DYNATUNE-XL Simulation Suite, preserving the original worksheets from 30 years ago. This version focuses on linear calculations, excluding the activation of bump-stops and utilizing the Base Tire Model with a partially linear cornering stiffness approach as the sole tire model. Despite these limitations, approximately 90% of customer-oriented vehicle behavior analysis can be evaluated through linear equations.
Linear models, often referred to as GENERIC in DYNATUNE-XL, serve as the backbone for understanding basic vehicle behavior, similar to linear bicycle models crucial for Electronic Stability Program (ESP) systems. Linear analysis is effective for exploring various aspects, such as aerodynamics, yaw damping, longitudinal load transfer, and weight distribution, influencing tire behavior, vehicle stability, and Under-/Oversteer behavior.
Ride calculations in the "LIGHT" version concentrate on Natural Frequencies, Bounce & Pitch Centers, and the calculation of Percentage Critical Damping. Tire grip level and aerodynamic data are limited to typical road car values.
Each DYNATUNE-XL MODULE includes a "USER" sheet, allowing users to perform additional custom calculations. The "LIGHT" version is designed primarily for novices, students, and enthusiasts interested in Vehicle Dynamics. While lacking non-linear effects, it serves as an optimal tool for grasping the basics of vehicle behavior without the complexity introduced by various non-linear components. This makes it an essential tool for automotive engineers working in the field of vehicle dynamics.

DYNATUNE-xL BASE VERSION
All you need to get the basics right .....

The DYNATUNE-XL R&H "BASE" MODULE builds upon the "LIGHT" Version, introducing a key feature — the ability to incorporate a non-linear bump-stop. This addition significantly influences RIDE & HANDLING characteristics, though it introduces increased complexity due to the non-linear behavior. The base non-linear calculation allows the investigation of specific points of interest for given parameters like Speed, Steering Wheel Angle, or a combination of Lateral and Longitudinal Acceleration. These points can be compared to results from the GENERIC linear calculation.
Ride calculations in the "BASE" Version offer additional features compared to the "LIGHT" Version, including Carpet Plots for selecting optimal front and rear wheel rate combinations. Additionally, there's the capability to calculate a linear Ride Step Input Response, a dynamic event in the time domain simulating a discrete obstacle, providing a more in-depth evaluation of transient damping effects on body and wheel movements. Another feature is the Ride Frequency Transfer Function, allowing frequency domain analysis and plotting frequency-related damping behavior of the front and rear body & wheels.
Tire grip levels now include slick tire friction coefficient levels, and aerodynamic data can reflect the effects of Non-Ride-Height dependent aerodynamic downforce coefficients.
The "BASE" Version equips users with the fundamental principles for non-linear analysis. It's suitable for those with a basic understanding of Vehicle Dynamics who seek to enhance their skills and delve into the intricate world of non-linear back-coupling involving aerodynamics, bump stops, riding heights, etc.
Starting from "BASE" Versions in the DYNATUNE-XL R&H MODULES for RELEASE 7.0 and above, various new USER-TOOLS have been introduced. Notable tools include the SUSPENSION DATA TOOL and TIRE DATA TOOL, providing foundational knowledge for Tire Data and Suspension Kinematic & Compliance Data. These tools suggest commonly used data based on a range of parameters for the selected Tire or Suspension. Users can plot their own tire data and automatically copy selected data to the corresponding input cells on the data sheets.
To enhance the accuracy of high lateral acceleration NON-LINEAR Calculations in the "BASE" Version and above, an "Enhanced Tire Model" is optionally available. It generates a full NON-LINEAR tire look-up table MAP for Slip Angle vs. Lateral Force vs. Vertical Force based on the partially linear "Basic Tire Model."

The DYNATUNE-XL R&H "PRO" MODULE does offer a remarkable user convenience feature, allowing users to save the currently used car data set as a Reference Data Set or reload the Reference Data Set in a dedicated RESULTS sheet. This feature facilitates quick comparisons between two or more variants, streamlining the analysis process. The RESULTS sheet not only summarizes all input and output data for the current and reference models but also provides room for additional data and custom post-processing.
In 7.0's "PRO" Version, a notable addition is the calculation procedures for PERFORMANCE ENVELOPES. These envelopes cover all combinations of lateral and longitudinal accelerations as a function of velocity and are visually represented as 3-dimensional Carpet Plots. Additionally, Understeer & Sideslip Angle Gradients are depicted in an isometric 3.5D projection, offering a unique and comprehensive understanding of vehicle behavior in multiple dimensions. These calculations can be executed in both LINEAR and NON-LINEAR modes.
The DYNATUNE-XL R&H "PRO" MODULE is tailored for professionals and enthusiasts who aim to delve deeply into understanding and learning about Vehicle Dynamics using OEM Standards and Test-Procedures, making it a powerful tool for in-depth analysis and insights.
