英文摘要: Maintainability design is an important content of complicated equipment development. By maintenance process simulation, maintainability defects can be detected and improved in early design stage. In this project, the technologies of physically based simulation and force feedback operation of disassembly and assembly process in maintainability design of complex equipment are studied systematically. The trajectory planning of maintenance tools with clearances based on dynamic response spectrum, the disassembly and assembly process simulation based on hybrid dimension modeling of irregular worn surfaces, the motion navigation of maintenance operations, and force feedback operation based on dynamics coupling calculation are proposed. Thus, the effect of physical factor, such as wear abrasion, contact and operation force on maintenance performance is simulated.Therefore, effective methods, technologies, and tools have been achieved for designer to analyze and evaluate maintenance performance in early stage. A maintenance simulation system has been developed, which has been applied to development of major navy equipment.14 papers have been published and indexed by SCI/EI, 3 patents of invention have been authorized, 1 software copyright has been obtained, and a second award of 2011 national science and technology progress has been obtained.
