轿车车门设计与碰撞分析
摘要
车门是车身结构中一个较复杂的总成。随着社会的发展和汽车工业的繁荣,汽车作为一种交通工具,在人们生活中起着举足轻重的作用。汽车车身是整车的重要组成部分,而车门作为车身的一个重要组成部分,又发挥着它所特定的功能。因而对车门也有特定的要求,如开关方便,玻璃升降方便、具有良好的密封、制造工艺性好等。由此可见,车门结构设计对车身乃至整车都有重大的影响。
本文运用CATIA软件进行车门各系统总成的设计与安装布置,并详细对防撞梁的耐撞性、抗弯性进行分析,并对其结构进行优化。运用LS-DYNA软件建立侧面碰撞有限元模型,根据C-NCAP侧面碰撞法规要求,进行侧面碰撞CAE仿真模拟,为进一步结构优化奠定了基础。

Abstract
Car body door is a plex in the body structure. With the development of society and the prosperity of the auto industry, automobile as a traffic tool, in people life plays an important role. The car body is an important part of the whole vehicle, and the doors as an important part of the car body, and play with specific functions. So on the door also have specific requirements, such as switching convenient, glass lift convenient, with good sealing, manufacturing technology. Therefore, the doors of body structure design and the vehicle has significant influence.
The use of software for each system CATIA the door of the design and installation arrangement and detailed to guard against the beams of the stamina to run, bent on analysis, and to optimize the use of its structure. The finite model for a certain automobile was created with the software LS-DYNA. According to the C-NCAP side impact rules the simulation analysis was finished,and it established the foundation for further structure optimization.
Topic words:Car door;Structure;Design;side puter simulation
