| Abstract: | The building-on method on numerical simulation model of vehicle bumper crash is expounded, and the dynamic explicit fmite element method is interpreted. The process of vehicle bumper crash is simulated with dynamic explicit finite dement method. A rational range of bumper thickness is put forward through studying absorbing energy rate of different thickness bumpers. |
