摘　　要：阐述车身设计正面碰撞多层传力路径的必要性,通过分析传统与新型3层传力路径的异同,重点介绍了如何设计正面碰撞传力路径来满足正面碰撞法规的要求,还简要介绍车身设计正面传力路径如何兼顾满足低速碰撞、维修保险及行人保护的要求。The necessity of multilayer load path for front crash is introduced. Through the analysis of the difference between the traditional and new 3 - layer load paths, how to design the load path to match the front crash requirement is emphasized. And how to consider the load path to match the requirement of low speed impact, RCAR, pedestrian protection is al- so mentioned. The detail of body structure design is illustrated by example.
