为解决复杂产品拆卸方向多样、路径多变问题,明确零件的具体拆卸路径角度,避免拆卸过程失稳造成损伤,提出一种基于拆卸稳定性的多路径几何可拆卸性分析方法。将现有干涉矩阵引入拆卸方向矩阵,得到全面的零件干涉检验结果和详细的零件拆卸路径角度,以动态转折干涉矩阵结合转折方向矩阵,描述零部件转折拆卸路径方向;提出拆卸梯度矩阵,确定零部件拆卸优先级,保证复杂产品零部件拆卸稳定性;采用全局坐标系(Global coordinate system,GCS)干涉检验方法、零件局部坐标系(Local coordinate system,LCS)干涉检验方法以及转折路径拆卸干涉检验方法,自动获取零件干涉情况,建立复杂产品的各类干涉矩阵模型;开发自动提取拆卸信息的拆卸原型系统,以实例验证拆卸分析的正确性,为后续复杂产品自动化拆卸提供可行方案。

To solve the problems of multiple disassembly directions and changeable paths for complex products,define the specific disassembly path angle of parts and avoid damage caused by unstable disassembly process,the method for analysis of multi-path geometric dismountability based on disassembly stability is proposed.The disassembly direction matrix is introduced into the existing interference matrix to obtain comprehensive part interference inspection results and detailed part disassembly path angle.The dynamic turning interference matrix is combined with the turning direction matrix to describe the turning disassembly path direction of the parts.The disassembly gradient matrix is proposed to determine the priority of disassembly of parts and ensure the stability of disassembly of complex products.The interference inspection method of the global coordinate system(GCS),local coordinate system(LCS)and turning path disassembly are adopted to automatically determine the interference of parts and establish various interference matrix models of complex products.The disassembly prototype system for automatically extracting disassembly information is developed to verify the correctness of disassembly analysis.This work provides a feasible solution for subsequent automated disassembly of complex products.
