摘　　要：白车身(BODYIN WHITE)刚度是评价车辆设计可靠性和整车安全性能的重要指标,白车身接头刚度分析是整车开发设计过程中必不可少的环节。利用某自主研发轿车为研究对象,建立其静态有限元分析模型,进行初步的白车身接头静刚度分析;并进行相关结构几何特性修改的刚度灵敏度研究,最后得出结论。BIW stiffness is an important criterion to evaluate vehicle reliability and safety. BIW bending and torsion stiffness analysis is an imperative step in auto development . In the research topic, the author takes an independent development car as study object to create its static FEA model and conduct its preliminary static analysis of bending and torsion stiffness and model; Finally get the conclusion.
