For the stress and vibration analysis of vehicle components by computer simulation, it is
necessary to find the forces acting on the vehicle components due to the road profile undulation. A precise modeling of tires is not easy due to nonlinear effects between tire-ground. Instead of
precise tire modeling, this paper proposes to regenerate the road profile, which preserves the
measured wheel accelerations with a linear tire model in the computer simulations. From the full
car example, the proposed method in this paper shows very nice results, and thus the new method seems well-suited in virtual driving simulations. The effort to improve durability of vehicle
components has been continued during test and development process. Computer aided durability
analysis techniques cut down time and money compared with experiment. In this paper, the
dynamic simulation of vehicle model was carried out with the MSC/ADAMS program and the
durability analysis of vehicle components was carried out with MSC/Fatigue program by using load profiles generated from dynamic simulation.
