摘要
利用LS-DYNA软件对不同孔腔半径的大小不同的空心钨球侵彻靶板过程进行了数值模拟研究。分析不同孔腔半径的大小不同的空心钨球贯穿靶板时的状态,发现孔腔半径r与钨球半径R的比值为0～0. 3时,钨球的剩余速度、剩余动能均达到最大,残余钨球的侵彻能力要高于实心钨球与其他比值的空心钨球。研究表明:当空心钨球孔腔半径r与钨球半径R比值为0～0. 3时,对靶板的侵彻效能有增益作用。
The numerical simulation of the penetration process of hollow tungsten spheres with different radius of cavity into the target plate was carried out by using LS-DYNA software. By analyzing the state of hollow tungsten ball with different size of cavity radius through the target plate, it is found that when the ratio of the radius of hole cavity r to the radius of tungsten sphere R is 0~0.3 , the residual velocity and residual kinetic energy of tungsten ball reach the maximum. The penetration ability of residual tungsten ball is higher than that of solid tungsten ball and hollow tungsten ball with other ratio. The results show that when the ratio of the cavity radius r and the radius R of the hollow tungsten sphere is 0~0.3 , the penetration efficiency of the target plate has a gain effect.
