相似模拟法在脱壳穿甲弹威力靶设计中的应用

Application of Similitude Method in the Design of Sabot Armor Piercing Projectile Power Target

反导舰炮的目标是正面迎攻反舰导弹 ,射击毁伤效果取决于脱壳穿甲弹钨芯与导弹的相对速度。此相对速度比弹丸的初速高 ,利用静止靶进行试验 ,火炮无法达到此速度。该文提出在弹丸所能达到的速度范围内 ,进行相似模拟试验。介绍用物理法则法和因次量纲法建立脱壳穿甲弹穿甲过程的相似模拟准则 ,并利用相似模拟准则来控制与穿甲过程有关的物理量 ,得出脱壳穿甲弹的威力靶设计准则 。

The target of anti missile shipborn gun is the anti warship missile which attacks directly towards the warship.The effect lies on the relative velocity between the projectile and the warship.This velocity is usually higher than the original speed of the projectile,and cannot be obtained in the test of stillness target. In this paper, the necessary simulation test is presented within the present projectile speed.The establishment of similitude rule of sabot armor piercing projectile polling on target by means of the method of physical law and dimension is reported . The similitude rule is used to control involved physical variables .The design rule of the target is given and applied to the design of the power target.
