Abstract:

For the problem of complex disassembly and assembly process and various system models in current aircraft maintenance training, the disassembly and assembly process model of aircraft components is established using the modeling method combining with hierarchical analysis and UML state machine. IDEF3 is used to establish the state, migration and constrained model of disassembly components, the unified expression of removing component model is regulated to improve the modeling efficiency. DSM is employed for the planning of various aircraft components, achieving an orderly logic expression of the disassembly target component, and establishing a high degree of simulation training model. Finally, the disassembly and assembly of a component on aircraft repair training platform is taken as an example to verify the validity of IDEF3 and DSM in the disassembly process simulation.

Key words: maintenance training, integrated definition 3, design structure matrix, disassembly and assembly model
