Road Load Simulation Using Effective Road Profile

This reearch presents a concept using effective road profile to calculate road loads. The method uses existing vehicle road load data, simplified vehicle dynamic model and simple tire model to create effective road profile. Then the simplified vehicle model is updated to reflect the vehicle changes of a new vehicle. Run the simplified new vehicle model to calculate road loads. The application of effective road profile in laboratory simulation is introduced. Preliminary CAE road load simulation using the effective road profile is presented.
