在飞机产品的设计过程中,标准件的装配设计是其中的一个重要环节。对装配特征进行分析,并运用CATIA的发布功能发布标准件的装配特征,通过基体模型特征信息的提取技术完成了对基体模型装配基准的创建,利用装配特征的信息匹配算法,并结合二次开发技术实现了标准件的快速装配。以螺栓螺母的虚拟装配为例,实现了标准件的装配特征的调用以及快速装配,大幅提高了装配设计效率。
In the design of aircraft products, the assembly of standard parts is an important part of the design. The assembly features were analyzed and the assembly features of standard parts were released by using the CATIA publishing function. The foundation model assembly baseline was created by the extraction of feature information of the substrate model. The information matching algorithm of the assembly features was used. Combined with the secondary development Technology to achieve the rapid assembly of standard parts. Taking the virtual assembly of bolts and nuts as an example, the assembly features of standard parts can be called and assembled quickly, which can greatly improve the efficiency of assembly design.
