  The current research of configurable product disassemblability focuses on disassemblability evaluation and disassembly sequence planning.Little work has been done on quantitative analysis of configurable product disassemblability.The disassemblability modeling technology for configurable product based on disassembly constraint relation weighted design structure matrix(DSM)is proposed.Major factors affecting the disassemblability of configurable product are analyzed,and the disassembling degrees between components in configurable product are obtained by calculating disassembly entropies such as joint type,joint quantity,disassembly path,disassembly accessibility and material compatibility.The disassembly constraint relation weighted DSM of configurable product is constructed and configuration modules are formed by matrix decomposition and tearing operations.The disassembly constraint relation in configuration modules is strong coupling,and the disassembly constraint relation between modules is weak coupling,and the disassemblability configuration model is constructed based on configuration module.Finally,taking a hydraulic forging press as an example,the decomposed weak coupling components are used as configuration modules alone,components with a strong coupling are aggregated into configuration modules,and the disassembly sequence of components inside configuration modules is optimized by tearing operation.A disassemblability configuration model of the hydraulic forging press is constructed.By researching the disassemblability modeling technology of product configuration design based on disassembly constraint relation weighted DSM,the disassembly property in maintenance,recycling and reuse of configurable product are optimized.
