破片斜侵彻靶板弹道极限速度分析

Analysing of Ballistic Limiting Velocities of Fragments Penetrating Target with A Angle

文中以球型破片为对象,采用实验和仿真方法研究了钨球斜侵彻不同结构靶板时,弹道极限速度随侵彻角的变化趋势。研究表明:钨球斜侵彻不同结构的靶板时,弹道极限速度随侵彻角的变化规律具有相似性;同时还研究了与钨球同质量、同体积的钢球斜侵彻同一结构靶板时,弹道极限速度随侵彻角的变化趋势,得出了相应结论:对于同一球型破片,直侵彻能贯穿的靶板,当侵彻角大于一定值时,即使侵彻速度很高也无法贯穿,直至破片碎裂嵌埋。上述结论,对战斗部威力设计、弹靶作用最佳位置的确定都具有十分重要的意义。

Through the test and imitation, discover the law of ballistic limiting velocities when tungsten Spheres penetrate different structure targets at different angles. And on the basis of the test .imitate the ballistic limiting velocities of steel spheres which have the same volume or quality with tungsten spheres when sphere-fragment penetrate the same structure target at different angles. And draw the correspondence conclusions:First, the laws that ballistic limiting velocities vary with penetrating angles are similar when fragments penetrate different structure targets; Second, the fragment that can penetrate target vertically can't penetrate the same target when having big penetrating angle even if it has high velocity. They are very important to design the power of warhead and locate exploding of bombs and targets.
