Abstract: At present， the sailorman have a little measure and time to do maintains training in real equipment and its failure effect is not very good. In allusion to this problem, this text has founded virtual maintenance exploitation flat for sailormen based on the need of maintenance training. The bounding-box and geometrical restriction method was adopted to solve the problems of collision detection. The key frame technology was adopted to simulate the motion of virtual human. The network communications mechanism based on Agent was founded to set up a collaborative virtual environment. The multi-roles collaborative model for virtual maintenance was presented to harmonize users how to collaborate. The mechanism that controls the concurrent conflict from the point of view of avoidance, detection and solution was proposed to clear up conflicts between the collaborative maintenance. In this flat, the computation is realtime, the developing work is simple while designing the scene, maintenance procedure, maintenance action, and operation instruction. Some different applications proved the exploitation flat had a good currency and can adapt to set up different virtual maintenance training systems easily.
