【摘要】 本文采用参数化变量技术建立轻型越野车车身骨架的有限元模型， 实现车身骨架映射网格的自动剖分， 所建模型能方便的修改结构和尺寸， 并可在短时间内对多种模型结构进行分析比较． 应用刚度敏感尺寸法能够迅速地找到结构刚度的薄弱环节， 在对整车骨架结构进行了有限元分析计算后， 根据分析结果提出了较好的结构改进方案．更多还原

【Abstract】 In this paper,Parameter variable technique is used to form finite element model for light jeep vehicle framework,and automatic mapped mesh generation for vehicle framework is realized.The created model can modify the structure and size conveniently,and compare many kinds of structure models in short time.The unsubstantial position of structure stiffness can be found rapidly by sensitive size method.The design scheme is improved according to the results of finite element analysis for full framework.更多还原
