Research on virtual haptic disassembly platform considering disassembly process

摘要

The speed of equipment repair and maintenance becomes a key factor in improving the production efficiency. Though the process of equipment disassembly is complex, long cycle and high cost, the combination of disassembly sequence planning and virtual disassembly platform can solve this problem effectively. The main contents of this paper include: (1) Petri net and genetic algorithm is used to solve the disassembly sequence planning and design a variety of disassembly paths. (2) In order to develop a virtual disassembly platform with more real experience, the physical properties of the equipment and parts are analyzed in the process of disassembly, and the real-time construction method of the physical model is studied; (3) Taking the reducer as an example, the platform of virtual disassembly with force feedback is developed and enhanced the real sense of virtual disassembly by added haptic interaction, which can finish the virtual disassembly under the guidance of the disassembly sequence optimized. Thus, virtual haptic disassembly platform considering disassembly process improves the effectiveness and authenticity of training, learning, and process validation of disassembly.
