This study was conducted to compare vehicle speed change and acceleration data from full scale testing to results generated by the Simulation Model Non-linear (SIMON) vehicle dynamic simulation model (version 2.0) within the Human Vehicle Environment (HVE) software. The study also sought to expand the body of existing curb impact tests and compare the present results to data from published literature. The results of the full scale testing of a 1996 Dodge Ram 1500 pickup are presented. Instrumented tests were performed at speeds up to approximately 6.7 m/s (15.0 mph) and at approach angles of 90° and 45°. SIMON was used to simulate the full scale testing conducted by the authors. The simulation results, including primarily vehicle speed change (delta-v), and accelerations are compared to the results of full scale testing. The appropriate method for modeling curb profile within SIMON version 2.0 was studied and is presented in this paper.
