水下系留平台扰动运动建模与仿真

Modeling and Simulation of Disturbance Motion for Submerged Mooring Platform

水下系留平台广泛应用于浮标、潜标等水文监测设备以及锚雷等水下作战平台,会受到海流作用而发生偏降、摆动和其他准周期性扰动运动,给所搭载的仪器设备或武器系统初始对准带来不利影响。本文以一种典型的水下系留平台为研究对象,建立了3自由度动力学模型,通过数学仿真研究了稳定海流作用下平台的平衡特性,以及扰动海流作用下平台的扰动运动特性,分析了平台总体参数、系留参数对扰动运动稳定性的影响规律,提出了减小扰动运动幅度,提高平台稳定性的措施。

Submerged mooring platform is widely applied to hydrological monitoring devices such as buoy and subsur- face buoy, and to underwater battle platform such as moorage mine. The platform will drift, descend, pitch and yaw, or even perform a complicated cycling motion to influence the initial calibration of the carried devices. In this paper, a typical submerged moorage platform is studied by dynamic modeling and simulation. A three-dimensional equation of motion is established to analyze the balance and disturbed motion of the horizontal submerged platform attached by fork connection. The effects of system parameters and mooring parameters on the stability of disturbed motion are analyzed via simulation, and some methods for improving the stability of the platform are presented.
