摘要
采用有限元分析软件Hypermesh/Optistruct建立了某汽车白车身有限元模型,通过对该有限元模型进行了弯曲刚度和扭转刚度分析,得到白车身的刚度情况.为白车身的结构优化设计提供了基础,进而提高了整车的舒适性和安全性.
In this paper, the FEM model of a car＇ s body-in-white is created with Hypermesh/Optistruct, an FEM software. Through the bending and torsion stiffness analysis of this FEM model, stiffness characteristics of body-in-white are acquired. It will supply the reference standard for structure optimization design. Moreover, it is helpful to improve the comfort and safety of the vehicle.
