Abstract

The frontal impact waveform is of great significance for occupant protection and automobile safety. According to the structure of the front engine room of the vehicle, a SUV frontal crash waveform is simplified by the simulation. The sensitivity analysis of the waveform characteristic parameters was carried out, and the influence of the large waveform characteristic parameters on the occupant injury was selected. The response surface model based on the energy absorbing area of sheet metal thickness as design variables, vehicle quality and waveform approximation coefficient as the target, parts invasion as constraints, using PSO particle swarm algorithm to optimize collision waveform, the optimization results show that the vehicle frontal impact waveform and the target waveform is closer to the wave approximation coefficient decreased by 51.1% and, vehicle quality is reduced by 0.7%, in the improvement of vehicle crash worthiness optimization at the same time, the requirement of the light weight era.
