摘要:随着科技的进一步发展,产品在趋于多样化、智能化的同时,也趋于复杂化。在新车型
的开发设计过程中,如何判断车门结构的合理性及车门结构静态强度和刚度,是一项十分重要
的工作。以南京 IV ECO 某车型的前车门为例, 在 Pro/ E 中进行三维建模和模型的简化,在
HYPERMESH 中进行网格划分,并利用 HYPERMESH 与 ANSYS 接口,对车门进行静力学分
析,计算车门刚度和强度较大和较小的位置,对车门设计具有一定的参考作用。

Abstract :With the development of technology , the products have e plex as well as diverse and
intelligent . In the development and design of a new style car , it is important to judge the rationality of the car
door structure as well as its strength and stiffness. The front car door of one style Nanjing IV ECO car is given
as an example in this paper. The model is built and simplified by PRO/ E , and then meshed in the HYPER
MESH. The static character of car door is analyzed by ANSYS through the interface of HYPRERMESH and
ANSYS. The weak and strong points are obtained ,which is useful for the car door design.
