Abstract: The virtual maintenance technology plays a vital role in the maintainability design and analysis of complex equipment, including ships and aircraft. In this paper, the application requirement of virtual maintenance simulation is analyzed in detail and an application system framework for ship maintenance simulation is put forward aiming at these demands. The system constitution and the functions of its all modules are elaborated. Specifically, the framework consists of four layers, i.e. data tier, function tier, interface tier, and UI tier. In the data tier, the storage of data with database or local folders is achieved. In the function tier, the management functions for several types of simulation data, the processing function for motion capture data, and the advanced analysis functions for visibility, accessibility, and comfort are devised. In the interface tier, the data integration function with the Team center (TC) platform is provided, which can download ship JT models from TC to the simulation system and upload simulation results and scene files to TC. In the interface tier, the humanization of interface is designed to optimize the interactive operation between users and the system. Finally, a prototype of ship virtual maintenance simulation application system is developed based on the Jack software. The implemented system lays foundation for ship virtual maintenance simulation data management as well as the utilization and the application of motion capture technique in virtual maintenance.
