水下锚系导弹发射系统运动研究

摘要

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.%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.
