水下锚系导弹发射系统运动研究

Study on Motion of Underwater Towed Missile Launch System

为研究水下锚系导弹发射系统在海流作用下的运动情况,基于Newton-Euler方法建立了水下导弹发射平台的运动模型;基于Ablow和Schechter方法建立了锚链的运动模型;在此基础上结合锚链运动的边界条件建立了系统的运动模型,并给出了相应的仿真算例。从仿真结果可以看出,通过该运动模型,可以很好的研究系统在海流作用下的运动情况。该模型的建立对水下锚系导弹发射系统的研制来说有参考价值。

To study the motion of the underwater towed missile launch system through the ocean current,its motion equations are established by using Newton-Euler method.The governing equations of cables are derived by using Ablow and Schechter method.Considered the boundary conditions of mooring cable＇s motion,the motion model of the system are adopted to predict its hydrodynamic performance.The established equations are then solved by using a central finite difference method.The simulation results show that the numerical scheme is effective and the motion model can provide reference for the development of underwater towed missile launch system.
