Abstract： Aiming at the problems of low eficiency and accuracy of disassembly interference detection due to the multi-part stacked structure devices，a DIA method was proposed based on DIE to improve the accuracy of disassembly information acquisition and shorten the disassembly time of parts. The disassembly information in the design model was extracted and quantified as a priority matrix through two-stage interference detection involving the boundary box and solid intersection. The dynamically changing disassembly information was accurately extracted by combining the dual coordinate system transformation of the assembly and parts. In order to verify the feasibility and effectiveness of this method， CAD design model experiments were conducted. The priority matrix generated by DIA and traditional interference detection methods were obtained and used as structural constraint information，which were input into the BOA-GA to search for the optimal disassembly sequence. The experimental results demonstrate that the accuracy of the priority matrix generated by DIA is increased by 28.57% compared with the traditional method，and the disassembly time of the optimal sequence is shortened by 3.31% ：
