摘　　要：针对机械部件在拆装过程中存在设备投资大、损耗程度高、危险性大、拆装效率低等问题,本文采用混合现实技术,设计出一套虚拟拆装系统.其中,拆装逻辑是拆装系统的核心,拆装系统的通用性取决于拆装逻辑的设计.为了解决虚拟拆装系统通用性差的问题,本文通过对常见机械模型的连接方式和装配关系进行分析和总结,设计出一种基于图遍历算法的数据结构来表达各个模型的逻辑关系,并针对特种阀门、六关节机械臂等设备的拆装进行实验.实验结果表明:该拆装逻辑解决了拆装顺序的可定义和通用性等问题,能够对模型部件按工艺流程进行虚拟拆解和装配,最终实现虚拟拆装系统的通用性.In the process of disassembly and assembly of mechanical parts,there are problems such as large equipment investment,high loss,high risk,and low disassembly efficiency,this study uses mixed reality technology to design a virtual disassembly and assembly system.Among them,the disassembly logic is the core of the disassembly system,and the universality of the disassembly system depends on the design of the disassembly logic.In order to solve the problem of poor universality of the virtual disassembly system,this study analyzes and summarizes the connection and assembly relationship of common mechanical models,and designs a graph-based traversal algorithm.The data structure is used to express the logical relationship of each model,and experiments are carried out on the disassembly and assembly of special valves and six-joint manipulator.The experimental results show that the disassembly and assembly logic solved the problem of definability and versatility of the disassembly and assembly sequence,and can perform virtual disassembly and assembly of the model components according to the process flow,and finally realize the versatility of the virtual disassembly and assembly system.
