摘　　要：以某轿车的保险杠为研究对象,运用显式动力学有限元理论,建立了保险杠的有限元模型,从满足低速碰撞性能的角度,分别采用低碳钢、高强度钢以及铝合金3种不同材料的保险杠进行基于耐撞性的轻量化研究。对保险杠的运动速度、加速度以及吸能量等进行了对比分析,验证了轻量化方案的可行性。Finite element theory is applied and a bumper of a car is used as the prototype. The finite element model is developed. Based on crashworthiness simulation, the performance of the bumper with different material is studied. Compared the velocities, accelerations and energy-absorbing ability of the bumper, the results of crashworthiness simulation verified the feasibility of the proposed model.
