摘　　要：在静力分析模型的基础上,利用Nastran提取结构内力,对电动轿车车身骨架进行多工况力流分析,介绍内力成分分析和应力成分分析的方法,从而建立构件的内力与车身实际所受载荷之间的联系,深入研究车身骨架的受力特点和身车结构的力流特性,为电动轿车车身结构概念设计提供参考。Force flow analysis of the electric-car body was carried out under multiple-load condition by using Nastran to extract the structural internal forces based on the static model. The internal force and stress composition methods were introduced.Then the connection between the internal forces of beams and the actual loads of car body was built. So the research on the loading features and force flow provides a significant reference for conceptual design of the electric-car body.
