摘　　要：汽车低速碰撞过程涉及到一些亟待解决的技术问题。立足于乘员的安全保护,通过仿真得出汽车前纵梁的理想碰撞曲线,结合吸能特性的评价参数得出前纵梁的评价方法。同时应用台车碰撞试验研究前纵梁的低速碰撞过程,得出各种真实碰撞性能曲线,与仿真结果比较,分析了影响前纵梁建模的各个参数,通过数学解析解与试验结果相比较来保证建模的准确性。Some automobile technical problems which involves in the low speed collision process urgently need to be solved. Based on crew member＇ s safekeeping of security, with computer simulation obtains ideal collision curve of front rails of the automobile, and unites endergonic characteristic appraisal parameter. The front rails assessment method is obtained specifically. Simultaneously uses the Trolley collision to research low speed collide process of the front rails, each kind of reality collision performance curve is obtained, and compared with them. Each parameter affects front rails modelling is discussed. Compares with the analytic solution as well as the experiment guaran- tees the modelling accurate.
