摘要
建立了汽车车身结构简化的有限元模型,计算并验证了简化模型的可行性;在选取了白车身不同位置的主断面后,进行了主断面力学特性对车身刚度影响的灵敏度分析,为汽车车身刚度优化设计提供了依据.
A FEM model of a influence of the characteristics sensitivity analysis, which is a car body structure is established. Feasibility of this model is verfied. The of the car＇ s main sections on car body stiffness is analyzed through the foundamental work for optimum design of car body stiffness.
