Vehicle Speed Changes and Accelerations Associated with Curb Impacts and a Comparison to HVE SIMON

Although collisions occurring in or near intersections often result in vehicles traversing curbing, few studies have addressed full-scale testing of these curb impacts. The current study compares vehicle speed change and acceleration data from full-scale testing to results generated by the SImulation MOdel Non-Linear (SIMON) vehicle dynamic simulation model within the Human Vehicle Environment (HVE) software. The study also compares the present results to data from published literature in order to establish if SIMON within HVE could be used as a tool to accurately predict the impact parameters between a vehicle and a curb. Full-scale testing of an instrumented 1996 Dodge Ram 1500 pickup was performed at speeds up to approximately 6.7 m/s (15 mph) and at approach angles of 90 deg and 45 deg. SIMON was used to simulate the full scale testing. The simulation results, including primarily vehicle speed change and accelerations, are compared to the results of full-scale testing. SIMON was validated for delta-v, against testing for speeds up to about 6.7 m/s. At speeds above 4.5 m/s, peak accelerations could not be modeled because they were significantly influenced by tire compression and energy absorption. Limitations of the simulation and additional parameters to be explored are discussed.
