Abstract: To address the problem of complicated geometry and topology and the constantly changing configurations during assembly of cables in complex mechatronic products,which made it difficult to simulate assembly process,the rigid and flexible hybrid assembly process simulation technology for complex mechatronic products was proposed.A physically based model was constructed to simulate the deformation of flexible cables in an accurate and interactive way.Then an information model was set up,which described the topology,geometry and physical properties of cables as well as organizing and storing the manipulation constraint information effectively.On this foundation,the collision detection for flexible cables was presented,and the real-time collision detection between flexible cables and rigid parts and self-collision of flexible cables was realized.The rigid and flexible hybrid assembly process model for complex mechatronic products was built to describe the simulation information of assembly process of flexible cables and rigid parts uniformly.A prototype system for rigid and flexible hybrid assembly process simulation was developed based on the above research,and the solution was validated by this system.
