Abstract: In view of the current situation of the teaching and training of the windlass for the crew, such as the complexity of the windlass equipment, the high price and the great danger of training, the application of virtual reality technology in the field of navigation simulation was analyzed,and the method of applying virtual reality technology in the interactive simulation system of the windlass was put forward.The rotation of each joint was calculated by using the principle of reverse dynamics followed by the skeleton movement in character animation, and the motion control and simulation of virtual human were realized. The heuristic search algorithm-A* algorithm was researched and used to realize the virtual humans automatic path finding function.Combining with the collision detection algorithm based on bounding box and mesh generation, the collision response between virtual human and windlass was realized.The developed three-dimensional windlass interactive system can simulate the whole process of the windlass operation, and it can completely meet the requirements of teaching and training.

Key words: ship engineering, virtual reality;vessel windlass, simulation system
