摘　　要：该文简要阐述了车身结构优化在偏置碰撞的遇到的问题及解决的方法,通过项目开发中偏置碰撞遇到的问题来探讨正面偏置碰撞结构安全性能提升的方法,以及研究正面偏置碰撞中关键部件纵梁的设计开发方法。通过对碰撞波形图的解读,保证轻量化的同时更改纵梁截面,同时设置诱导特征,实现整车重量增加后碰撞安全目标的达成,进一步证明仿真在结构设计的重要性。This paper describes the problems encountered in offset collision of body structure optimization and the solutions,Through the problems encountered in offset collision in project development,this paper discusses the methods of improving the safety performance of frontal offset collision structure and the design and development method of longitudinal,the key component in frontal offset collision.By interpreting the crash waveform to ensure lightweight while changing the cross section of the longitudinal beam,and setting inducement features to achieve the crash safety goal after increasing the weight of the entire vehicle,it further proves the importance of simulation in structural design.
