Design and Implementation of Virtual Maintenance Training System Based on Cortona3D

With the rapid development of the virtual reality technology, shortcomings of the conventional real equipments maintenance training can be remedied by adopting virtual maintenance training technology. This paper reviews the significance and development status of virtual maintenance based on virtual reality technology, including the basic functions and module design of equipments virtual maintenance training system, such as construction and principle learning module, real component level dismantlement and assemble module, decomposability and combining, fault check and removing module, control and examining module, etc. The basic data necessary to realize the virtual maintenance training system are identified and how to obtain these data is discussed, including maintenance items, maintenance training contents, fault database and maintenance training behavior simulation. On the basis of above results, the system framework is designed, which can be used for the development and integration of all kinds of equipment virtual maintenance training systems.
