摘要
设计重用是提高设计效率,缩短设计周期的有效手段。分析了航空件焊接夹具设计的重用层次,介绍了过程重用、装配关系重用、基于行业知识的零部件重用以及特征重用的理论基础和实现方法。利用重用技术,在CATIA平台上实现了航空件如导管、副油箱等产品的焊接夹具设计过程的自动化,有效的提高了设计效率。
Design reuse is an efficient way to enhance the design efficiency and shorten the design period. Based on the analysis of design reuse levels in welding fixture design of aeroplane parts, several methods are discussed, including design process reuse, assembly relation reuse, parts and components reuse and feature feud. A welding fixture CAD system has been developed on CATIA to automatism the design process, and has enhanced the design efficiency greatly.
