A multi-body simulation coupled with a tire model enables the prediction of forces generated on a vehicle when driven over a rough road profile. As the durability of a vehicle depends on these generated forces, the accuracy of the predicted forces is a crucial factor in assessing durability. A new test setup has been used to evaluate the accuracy of the simulation. Due to good reproducibility, the results from physical testing and simulation can be compared in the time domain. This time domain comparison makes it possible to detect any problems associated with the simulation which need to be improved. This new evaluation method is very suitable to full vehicle simulations involving rough road profiles. It was also confirmed that the suspension model with tire model evaluated in this project had an adequate capability for curb strike simulation by a full vehicle.
