| 摘 要： | 建立了面向装配过程稳定性分析的装配模型。从装配操作的稳定性和子装配体稳定位姿两方面分析装配过程的稳定性．基于支撑矩阵和增强邻接矩阵构建拆卸操作稳定判别算法来反推装配操作的稳定性．基于软联接图，通过计算子装配体内部自由度的方法来求解子装配体稳定的装配位姿．该方法被用于虚拟装配／拆卸过程中，开发了虚拟环境下的装配／拆卸原型系统，以支持拟实的装配／拆卸规划．

| Abstract: | A special assembly model for stability of assembly process was built. The stability analysis of assembly process was implemented from the two respects of the stability of components assembled and the stable location and pose of moving subassemblies. The judgment algorithm of stability of disassembly operations was given based on the support matrix and the extended adjacency matrix to derive the stability of assembly operations. The internal degree of freedom of subassembly was computed based on the soft connecting graph to get the stable assembly location and pose. The above methods were applied to the virtual assembly/disassembly process, and the prototype system (VirDFA) of assembly/disassembly planning under virtual environment were developed to support the real assembly/disassembly planning. |
