摘　　要：深海释放器是海洋观测仪器、海洋工程中关键设备。研究考虑海流、释放器部件碰撞等因素的深海释放器释放过程的动力学情况,采用多体动力方法建立某深海释放机构的动力学模型,模拟释放机构的释放过程中各构件的运动情况和运动轨迹,计算释放机构在释放过程各组成构件的运动参数,该方法可以用于模拟深海释放器释放过程状况,分析释放器失效的原因和指导释放机构的设计。Deep-sea release mechanism is an essential equipment for ocean exploration and ocean engi- neering. Releasing process of deep-sea acoustic releaser is studied considering sea current, impacts between components. Multibody method is used to develop the dynamic model of this mechanism and simulate the motion of releaser. The kinematic parameters of different components and trajectory of releaser are obtained. This method can be used to understand the motions for releasers and analyze the reason of failure. This work is helpful for design and development for deep sea release mechanism.
