[Abstract]:The use of virtual reality technology can improve the level of maintenance training, and solve the situation that traditional maintenance training methods lag behind.Based on the research of the key technology of virtual maintenance disassembly process planning and simulation system, a prototype system of virtual maintenance disassembly process planning and simulation is constructed, which provides an auxiliary platform for virtual maintenance training and simulation.Aiming at the construction of virtual maintenance scene, this paper gives two strategies for developing virtual maintenance scene. Aiming at the incompatibility between CAD system and VR reality system, the model conversion technology and model optimization technology are studied.On the basis of analyzing the research of disassembly sequence planning by domestic and foreign scholars, the Petri net disassembly sequence planning based on part constraint relation is studied, and the characteristic of the model is analyzed and verified. The data chain list of disassembly sequence is established with the obtained disassembly sequence.Store part information.On the basis of disassembly sequence planning, the problem of disassembly path planning in EON environment is studied. In order to ensure the validity of disassembly process, collision detection is carried out in real time, and the key points of disassembly path are recorded.The information of the key points of the path is assigned to the disassembly sequence data link list, which provides the support for the simulation of the disassembly process. The interactive control of the scene and the objects in the virtual maintenance system is studied, and the TPO viewpoint change function is designed.According to the disassembly behavior of the maintenance object, the view change model is established, and the interactive control method of six degrees of freedom motion of the disassembly object is designed.Finally, after studying the above technologies, the prototype system is developed on the Windows XP system using the virtual reality development platform EON Studio5.0, VC 6.0 high-level programming language and Script script.This prototype system can complete the typical technical links of virtual maintenance and disassembly, such as loading model, disassembly path planning, disassembly process simulation and so on.
