Abstract

Based on the injury estimate system of vehicle occupant in emergency brake is established. The vehicle occupant restraint system model is established based on software called MADYMO for front impact simulation, the system consists of body, safety belts and a dummy. After adjusting the model, occupant head and chest injury curves and injury values such as HIC, T3MS and Thpc are got, which are close to test ones contrasted with the vehicle impact test. The model is used to compute the simulation of vehicle emergency brake with the assumption of assumptive approximate decelerate speed. Then different types of safety belts and cushion angles related to injury values are got. Simulation analyzing reveals that three-point safety belts can protect occupant better and augmenting the cushion angle can reduce occupants´ injury values.
