摘　　要：在汽车开发的概念设计阶段,需要合理地设计前舱外型面与前舱零件间的间隙,即前舱吸能空间,以满足行人头部保护的要求。文章以某车型为例,通过理论计算的方法,对满足行人头部保护要求的前舱吸能空间进行估算,并建立了详细的行人头部碰撞有限元仿真分析模型,验证了估算得到的前舱吸能空间的合理性。In the early stages of the car development process, it is very important to determine the necessary crash depth, the clearance between the hood and the underlying parts, considering pe- destrian head protection. The paper takes a vehicle model as an example and proposes a method to es- timate the necessary crash depth during the early development stages. The effectiveness of the proposed method for pedestrian head protection is verified by detailed finite element analysis.
