对称零部件快速装配设计方法研究
Research on Rapid Assembly Design Method for Symmetrical Parts and Components

为克服使用CATIA系统镜像功能进行对称零部件装配设计时会带来数据冗余、零部件命名编号不符合设计要求的缺点,提出了一种对称零部件快速装配设计方法。该方法采用同一数据源零部件自动识别和零部件分类实例化技术,实现了对称零部件的快速装配设计。以CATIA V5系统为平台,开发了对称零部件快速装配设计工具插件,通过某飞机机翼骨架的快速装配设计实例,验证了方法的有效性。结果表明,该方法能提高对称零部件的装配效率,降低设计成本。
Data redundancy and improper rules for parts and components naming will happen when the mirror function in the CATIA system is used for the assembly design of symmetrical parts and components. In order to overcome the aforementioned disadvantages, a rapid assembly design method for symmetrical parts and components is proposed. In this method, parts and components with the same reference source are automatically identified. Instantiation of parts and components is carried out according to their categories. The rapid assembly design method is realized on the CATIA V5 system. The effectiveness of the method is verified by the rapid assembly design of an aircraft wing structural framework. Results indicate that the present method can improve the assembly efficiency of symmetrical parts and components, decrease the designers' workload, shorten the engineering product design cycle and reduce design cost
