The varying target component virtual disassembly simulation technology is presented to support the disassembly analysis and feedback in product design for disassembly by a 3D visualization way. The disassembly weighted hybrid graph (DWHG) is constructed to describe the constraints and disassembly priority relationships among constituting components of product. In addition, a hierarchical recursive construction method is proposed to enable the rapid construction of DWHG for complex products. Based on the DWHG, varying target component disassembly sequences are generated by a recursive reasoning method. To facilitate the virtual disassembly simulation, the component disassembly path is translated into the discrete critical path points and the critical path point recognition technology is proposed to obtain them. The disassembly simulation of components could be controlled through the transform of pose matrix. Finally, a case study proves the validity and feasibility of the proposed method.
