摘要: 基于不可压缩流体的非定常势流理论建立了空投水雷入水冲击力计算的数学模型，对水雷的入水冲击力进行了计算。仿真结果表明,入水冲击力的数量级是相当大的；最大入水冲击力随着入水速度的增大而迅速增大，与入水速度的平方成正比例关系；最大轴向入水冲击力随着入水角度的增大而增大；最大法向入水冲击力随着入水角度的增大而减小。

Abstract: Based on the unsteady potential flow theory of incompressible liquid, a model of water-entry impact force for air-launched mine was presented, and the water-entry impact force was calculated. Simulation results show that the water-entry impact force is huge, the maximal impact force increases with the water-entry velocity and is directly proportional to the square of water-entry velocity, the maximal axial impact force increases with the water-entry angle, and the maximal normal impact force decreases with the water-entry angle.
