针对锚雷战斗部断索自沉的保险功能,首先建立其沉雷运动数学模型,然后介绍了开孔器的结构设计,最后结合实例,对锚雷战斗部断索后的沉雷运动进行仿真预报。结果表明,战斗部在设定水深开始注水后,可在露出水面之前沉没,从而保证了水雷的隐蔽性和安全性。 Aiming at the insurance function of broken cable self-sinking in the anchor and mine warhead, the mathematical model of the sinking movement is first established. Then the structure design of the hole opener is introduced. Finally, with the example, the mine movement of the anchorage mine warhead is simulated and forecast. The results show that the warhead can sink before the water surface is exposed after the water depth has been set, so as to ensure the mines’ concealment and safety.
