The early evaluation of vehicle and subsystem concepts, the reduction of the number of necessary test runs, the verification of multiple variants and the possibilities to do quick parameter studies are critical issues in modern engineering where sophisticated simulation methods are used to improve and to fasten the engineering process. Given the future legal requirements for CO2 emissions and the correlated measures to improve the aerodynamics of the vehicle the evaluation of ground clearance is one of the most important topics for the development of future passenger cars. This paper describes how the multi-body simulation environment at GM Europe (GME) - consisting of the Hyperworks/MotionView pre-processing, the Virtual Modeling Components (ViMC) library and the Adams solver - is used to simulate ground clearance load cases (e.g. driving over curbs, ramps and speed humps with distinct speed and with distinct steering angles).
