沉底雷撞击海底时的过载问题是空投沉底雷总体关注的重点问题之一。研究了沉底雷入水后在水中的速度变化,计算了水雷在不同水深条件下的击底速度,在此基础上研究了水雷以一定初速度撞击不同介质海底的过载。最后举例对沉底雷撞击海底时的过载进行了计算。 The problem of overloading when the submerged mine strikes the sea floor is one of the key issues that the emplacement of the submarine mounted mine is of general concern. The velocity change of submerged mine into water was studied. The bottoming speed of mines under different water depths was calculated. Based on this, the overburden of mines at different initial velocity was studied. Finally, an example is given to calculate the overloading when a sinking and grounding lightning strikes the sea floor.
