Modified Road Profile Generation Using Road-Wheel FRF and Simulation of Dynamic Load Transfer in Vehicle Suspension

For the stress and durability analysis of vehicle components with computer simulation, it is necessary to find forces acting on the vehicle components due to the road profile undulation. In this study, road profiles are regenerated by preserving the same PSD of wheel responses. The frequency response function between road and wheel, the digital signal processing method, and DADS program are used. Simulation results of load transfer at suspension components using this virtual road profiles are presented.
