车身概念设计系统的开发及关键技术

Efficiency of the traditional automotive body design method is very low at phase of automotive body structure concept design. So the new automotive body structure concept design system was developed on UG. The Characteristics and workflow was introduced, the key techniques were described at some length. The user interface was created by Wizard UI technique and the template of car body was created by Knowledge Fusion technique, the database was build by Spreadsheet technology and the functions of system were realized by UG/OPEN API functions. The stiffness and model of certain car were analyzed by system and compared with result of detailed result. The result meets the concept design requirement. It proves the effective and reliability and improves efficiency of the design greatly.
