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。
Based on the analysis of the motion force of underwater airdrop mine under the unpowered movement, the mathematical model of the underwater initial trajectory is established and the trajectory simulation is realized by Matlab software. The simulation results show that the initial trajectory within a certain range of depth shows the characteristics of reverse flow when the airdrop mine under study has horizontal uniform water flow and water entry angle, which is beneficial to reduce the scattering distance. In the absence of horizontal uniform flow , The impact of the increase of water-in angle on the spreading distance is more obvious than the increase of the speed of water-in-air mines into the water.
