Today’s automotive companies are working communization for parts to shorten the development cycle and cost competitiveness as a policy. Even if parts are communized, high-performance tires and suspension tuning are required to enhance R&H performance and trim height is set up lowering for styling. The service loads transmitted to suspension and body structure are related to suspension types, tire characteristics and wheel travel values. Especially, wheel travel values are the important factor for vertical loads. Since the loads to WFT on the other hand aren’t changed considerably according to wheel travel values. To investigate the load performance for vehicles which have different wheel travel values, this paper presents the modeling methods of nonlinear components for building analytical vehicle models which are simulated on pothole roads and rough random roads such as Belgian block and estimates peak load values on pothole roads and pseudo damage levels on Belgian block road.
