A Product Disassembly Sequence Planning Method Based on Disassembly Stability

针对拆卸过程稳定性问题,以及复杂产品拆卸图模型构建困难和效率低等不足,提出一种面向拆卸稳定性的拆卸序列规划方法。充分分析面向绿色制造和循环经济的拆卸的特点和原则;通过分析产品的CAD模型,构建一种集零部件类型、零部件可行拆卸方向集、零部件拆卸空间制约矩阵、零部件接触矩阵、零部件自由度约束矩阵等于一体的产品拆卸信息分析模型;提出相关拆卸优先原则和稳定性原则;给出基于拆卸过程稳定性的产品拆卸序列规划算法;通过一个完全拆卸和目标零件拆卸实例验证该算法的可行性、实用性。

Focusing on the stability of disassembly process and the hmitation of graph-based disassembly model for complex products, a new disassembly sequence planning（DSP） method based on disassembly stability is presented. The characteristics and principles of disassembly for green manufacturing and circular economy are analyzed. A new disassembly information analysis model based on set and matrix is constructed under the analysis of the product CAD model, which includes component types, the feasible disassembly direction sets of components, the component dismantling space restriction matrix, the component contact matrix and the component degree of freedom （DOF） constraint matrix. The priority and stability principles are also presented. Furthermore, the algorithm of this new DSP method is proposed. The feasibility and practicability of the presented method is verified by a case of both complete disassembly and selected disassembly.
