摘　　要：潜伏于水中的导弹武器一般采用多联装发射-储运一体装置,与传统主动攻击型水雷相比具有更复杂的外形。为分析锚系型水下潜伏平台在海流作用下的扰动运动,需计算其全部流体动力系数。基于CFD方法,建立一套复杂外形水下潜伏平台的流体动力计算方法,计算一种四联装水下潜伏平台的位置力、阻尼力和附加质量特性,可为水下潜伏平台扰动运动仿真提供全套流体动力参数。计算方法可供其他复杂外形水下航行器和结构物流体动力特性计算参考。Missile weapons lurking in the water generally use an integrated device for launching,storage and transportation of multiple units,which has a more complex appearance than the traditional active attack mines.In order to analyze the disturbance motion of the anchored underwater lurking platform under the action of ocean currents,it is necessary to calculate all its hydrodynamic coefficients.Based on the CFD method,a set of hydrodynamic calculation methods for underwater submersible platforms with complex shapes,and calculates the position force,damping force and additional mass coefficients of a quadruple underwater lurking platform are calculated which can provide a full set of fluid dynamic parameters for the simulation of underwater lurking platform disturbance motion.The calculation method can be used as a reference for calculating the hydrodynamic characteristics of other complex-shaped underwater vessels and structures.
