Introduction

Two organizations from Delft (TNO and Delft University) and Aachen (ika and fka) are jointly preparing a two-day-course on Vehicle Dynamics Simulation and Testing to be held in Aachen on July 14 -16, 1999. This event is designed to combine lectures, simulation practices and driving tests with concept vehicles on the ika test track. Course attendees will have the opportunity to work with simulation tools and to perform driving tests themselves.

The course will at first concentrate on theoretical backgrounds of vehicle lateral and vertical dynamics. The following simulation and practice courses will thereafter give a more in-depth understanding of the theoretical contents of vehicle dynamics. The course is designed to deliver a basic knowledge of vehicle lateral and vertical dynamics and therefore it is aimed at engineers in automotive and supplier industry who require an introduction in vehicle dynamics in testing and simulation.

8.30 Lecture: Basics of tyre technology and tyre behaviour
• physics of the pneumatic tyre
• steady state tyre performance and empirical models
• transient tyre behaviour
• the impact of tyre characteristics on vehicle performance
9.30 Lecture: Basics of lateral dynamics
• single track and two track model
• evaluation methods for driving performance/driving manoeuvres in simulation and testing
• influence of vehicle, suspension and chassis design
11.30 Simulation practice:
• tyre models and tyre characteristics,
• simple models for lateral dynamics in MATLAB/Simulink (single track vehicle model)
12.30 Lunch
13.30 Lecture: Modern vehicle dynamics systems, technology and influence
• four-wheel steering
• four-wheel drive
• vehicledynamicscontrol
14.30 Simulation practices:
• four-wheel steering with MATLAB
• vehicle dynamics control with ADAMS
16.45 Teamwork:
Participants will jointly work on vehicle dynamics
The idea is to focus on the integration of VDC and 4WS

9.00 Lecture: Basics of vertical dynamics
• components of spring and damper system
• models for vertical dynamics
• valuation methods for the ride performance (driving manoeuvres) in simulation and testing
10.30 Lecture:
• basics tyre influence on ride performance

11.00 Simulation practice: Vertical dynamics
• Simple models in MATLAB/Simulink
• model of the DAS-vehicle in MATLAB/Simulink
12.00 Lunch
13.00 Practice: Driving manoeuvres on the ika test track
Three groups with different practices, rotation around tests:
1. steady state cornering and J-turn (AEF and DAS vehicle)
2. lane change and slalom test (vehicles with 4 WS, 4WD, DAS vehicle and VDC)
3. Vertical dynamics on uneven roads (vehicles with new damping systems)
15.30 Presentation of the teamwork
16.00 Summary and conclusions
