装配结构树是数字化装配中装配序列规划的起点,质量的优劣直接决定装配序列优化的时间和效率。为提高装配序列规划的效率,提出建立综合零部件基本属性信息、产品层次信息、关系信息和连接信息的集成装配模型,并把基础件作为装配结构树中子装配体的产生载体,结合分层理论来研究装配结构树的生成算法。在上述研究的基础上,开发了原型系统,进行多个大型、复杂产品的装配序列规划验证,不仅结果正确、可靠,而且装配结构树产生的效率大大提高。如减速器装配结构树的产生只需3 min。因此,该模型和算法能实现复杂产品装配结构树的计算机自动规划,可广泛应用于汽车、机器人等多零件产品的装配顺序规划。
The assembly tree is the starting point for the assembly sequence planning in digital assembly. The quality of the assembly tree directly determines the time and efficiency of assembly sequence optimization. In order to improve the efficiency of assembly sequence planning, an integrated assembly model of basic attribute information, product level information, relationship information and connection information is put forward, and the basic part is taken as the carrier of neutron assembly of assembly tree, Theory to study the assembly tree generation algorithm. On the basis of the above research, the prototype system was developed to verify the assembly sequence planning of several large and complex products. The result is not only correct but also reliable, and the efficiency of assembly tree is greatly improved. Such as reducer assembly tree generation only 3 min. Therefore, the model and algorithm can realize computer automatic programming of complex product assembly tree and can be widely applied to assembly sequence planning of multi-part products such as automobile and robot.
