介绍了一种全新的车身结构概念设计系统的特点以及设计流程,阐述了该系统采用的关键技术,如设计向导用户界面、知识熔接技术、电子表格技术等。利用该系统对某款轿车进行了刚度与模态分析,通过与详细设计结果的对比可知,结果基本符合概念设计要求。利用该系统对该轿车进行了优化,证明了系统的有效性及可靠性。

英文摘要：

Characteristic of a brand new body structure concept design system and design flow are introduced in the paper, key techniques applied in the system are outlined, e.g. designing wizard user interface, knowledge welding technology, Excel technology, etc..Stiffness and modal analysis of a car is made with this system. It is concluded from comparison with detailed design results that the result basically meets the concept design requirement. After optimization of the car with the system, validity and reliability of the design system are verified.
