摘　　要：浮标在水下上浮过程中的运动姿态会影响其接收阵在水面的展开效果,进而影响其对空中目标的探测能力。针对该问题,对浮标从开始上浮到上浮至水面的全运动过程进行了建模与仿真,详细分析了初速、重心、浮力等因素对浮标运动轨迹的影响,得到结论如下:在自由上浮的情况下,浮标作垂直上浮运动,在开始阶段速度逐渐增大,最终达平衡速度,并保持此平衡速度直至浮出水面;初速度和平台速度只影响浮标初始阶段的运动,最终其运动参数与基准运动轨迹趋于一致;增大正浮力可使浮标具有更高的出水速度,同时缩短上浮运动时间,而增大浮重心距对浮标运动姿态没有太大影响;海流对浮标上浮姿态影响不大,但会在水平方向产生较大的位移。The motion attitude of the buoy in the process of floating upwards underwater will affect the deployment effect of its receiving array on the water surface,and then affect its ability to detect air targets.In order to solve this problem,this paper models and simulates the whole motion process of the buoy from the beginning of floating upward to the status of surfacing.On analyzing the influences of initial velocity,gravity center,buoyancy and other factors on the trajectory in detail,we have drawn several conclusions as below.Firstly,under the condition of free floating,the buoy moves vertically,and its speed increases gradually in the beginning,while finally reaches the equilibrium speed and moves at this equilibrium speed until reaching the surface.Secondly,the initial velocity and platform velocity only affect the initial motion of the buoy,and finally the motion parameters tend to be consistent with the reference motion trajectory.Thirdly,increasing positive buoyancy can make the buoy more quick at surfacing speed and shorten the floating time,but increasing the distance to the floating center of gravity has little effect on the buoy’s motion attitude.Fourthly,the current has little effect on the floating attitude of the buoy,but it will produce great displacement in the horizontal direction.
