基于目标拆卸的虚拟拆装过程建模

Modeling of Virtual Assembly and Disassembly Process Based on Selective Disassembly

针对目前基于层次关系模型和关联关系模型的虚拟拆装系统中未考虑目标拆卸的问题,在原有层次关系模型基础上引入跳跃拆卸路径的概念,对基于层次关系模型和关联关系模型的拆装结构模型进行了完善和优化。对引入跳跃拆卸路径后的拆卸模型进行序列规划,并针对拆装决策过程中拆装单元的组合与还原问题进行论述,最后建立基于关联关系模型的目标拆卸算法。以船用分油机进行实例验证,验证结果表明该模型能够很好地解决目标拆卸的问题,对相关应用系统开发具有一定的参考价值。

To solve the problem of not considering the selective disassembly in the current virtual disassembly system based on the hierarchy model and relationship model, the skipping disassembly path was introduced which developed and optimized the original hierarchy model and relationship model. The sequence planning of the disassembly model after introducing the shipping disassembly path was carried out. And the combination and reduction of disassembling units in the course of disassembly decision was described. Finally, the selective disassembly algorithm was established based on the relationship model. With the marine oil separator for example verification, the verification results showed that the model could solve the problem of selective disassembly very well. So this work has a certain reference value for the development of the related application system.
