%X 分析自由降落式救生艇虚拟培训系统的功能需求，设计单人与虚拟人间、多人间的两种协同工作方式；建立吊艇臂的运动数学模型，模拟吊艇臂与液压顶柱之间的关联运动；应用并改进经典的质点-弹簧系统模型，较逼真地模拟了救生艇中不同材料柔性绳索的运动效果；应用三维建模软件和Unity3D引擎构建火灾、大风浪天气以及沉船等海上场景，可模拟救生演习的一系列过程.研发的自由降落式救生艇虚拟培训系统运行稳定，培训效果良好.</br>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.
