Introduction

Two organisations from Delft (TNO and Delft University) and Aachen (ika and fka) have jointly held two-day-courses on Vehicle Dynamics Simulation and Testing in 1999. Because of the success of this courses, it has been decided to repeat these courses on June 26-28, 2000 in Aachen at the ika, and a second time in Lelystad the Netherlands on September 27-29, 2000 on the testtrack of the Dutch Vehicle Technology and Information centre (RDW). As the previous ones, these events are designed to combine lectures, simulation practices and driving tests with concept vehicles on the brandnew test track including a 100 meter diameter platform, a straight of 35 meter width and several special low friction facilities. Course attendees will have the opportunity to work with simulation tools and to perform driving tests themselves. The courses 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 courses are designed to deliver a basic knowledge of vehicle lateral and vertical dynamics and therefore are aimed at engineers in automotive and supplier industry who require an introduction in vehicle dynamics in testing and simulation.
