摘　　要：在对一种空投水雷水下无动力运动过程中运动受力分析的基础上,建立了研究其水下初始弹道的运动数学模型,并用Matlab软件编写实现了弹道仿真。仿真计算表明:研究的空投水雷在有水平均匀水流和入水角的情况下,一定深度范围内的初始弹道表现出逆流向运动特性,对减小散布距离有一定好处;在没有水平均匀水流情况下,入水角的增加比增大空投水雷入水速度对散布距离的影响更明显。The movement mathematical model of the underwater initial trajectory is established based on the stress analysis for the airdrop mine in the process of underwater movement,and the trajectory simulation is actualized using the Matlab software.The simulating calculation result show that the airdrop mine under the situation of the horizontal homogeneous current flow and water entry angle,the initial trajectory in the definite depth range shows the reverse flow direction movement characteristic,which benefits the reduction of the spread distance;without the situation of the horizontal homogeneous current flow,increasing the water entry angle has more influence than increasing the water entry velocity on the spread distance obviously.
