Virtual maintenance environment layout planning research based on GA

Virtual maintenance environment is the workplace of virtual repair disassembly and assembly and an important part of maintenance virtual realization. During the maintenance disassembly process it is easy to come to the condition that disassembled parts are complex and the disassembled parts are too many. In order to achieve good display results, resolve virtual maintenance disassembly parts and components layout problems in the 3-dimensions (3D) environment, the paper classifies the components according to the application of hierarchical division. As a result, 3D spatial distribution is simplified to multiple 2-dimensional (2D) layouts, to reduce the complexity of the layout. In the 2D layout, genetic algorithm is used to optimize for improving the quality of layout. Finally this paper applies the method to Aero-Engine high pressure compressor virtual disassembly parts and components layout, indicating that it is feasible.
