Abstract

This paper analyzed the functional requirements of the free-fall lifeboat virtual training system, and designed two types of cooperative work: one person with virtual human and multi-human. The mathematical model of davit arm movement was established to simulate the motion of the davit arm and the hydraulic pillar. The classical particle-spring system model was applied and improved to simulate the motion of the flexible rope of different materials in the system. By using 3D modeling software and Unity3D engine, the fire, stormy weather, wreck and other sea scenes were built and life-saving exercise processes were simulated. The proposed free fall lifeboat virtual training system is stable, and has a good training effect.

Key words： free fall lifeboat; Unity 3D; virtual reality; training system
