利用计算机仿真方法研究汽车保险杠系统的耐撞性。在三维机械设计软件CATIA中建立整车及保险杠系统的三维CAD模型，并在Hyper Mesh软件中进行前处理，进而建立有限元模型；在PamCrash软件中进行碰撞过程仿真求解，将仿真结果与实车碰撞数据进行对比，验证了模型的正确性；最后进行保险杠系统低速碰撞过程仿真，通过仿真可预测出汽车保险杠系统发生碰撞时的位移和变形，为保险杠系统的设计改进提供参考。
利用計算機倣真方法研究汽車保險槓繫統的耐撞性。在三維機械設計軟件CATIA中建立整車及保險槓繫統的三維CAD模型，併在Hyper Mesh軟件中進行前處理，進而建立有限元模型；在PamCrash軟件中進行踫撞過程倣真求解，將倣真結果與實車踫撞數據進行對比，驗證瞭模型的正確性；最後進行保險槓繫統低速踫撞過程倣真，通過倣真可預測齣汽車保險槓繫統髮生踫撞時的位移和變形，為保險槓繫統的設計改進提供參攷。

A computer simulation method is used to study crashworthiness of car bumper systems. A three-dimensional model of the car and its bumper system is established in CATIA software. Pre-treat- ment is done in HyperMesh and a finite element model is established. Simulation of the car crash process is then performed in PamCrash. The simulation results are compared with real test to verify accuracy of the finite element model. Finally, a low-speed crash simulation is carried out. Crash displacement and de- formation of the car bumper system can be predicted using simulation method, which provides a reference to the design and improvement of car bumper systems.
