摘要
使用二维有限元法 ,研究了6mm、8 5mm的预制破片 (钨珠、钢珠 )以不同速度在稠密气体中飞行时的破损问题 ,初步确定了珠子破损的阈值速度。研究表明 ,破损的程度与珠子的速度、材料、大小有密切关系。同时还研究了破损了的破片对 6mm厚钢靶的穿透能力。
Damage of different balls with the diameters of 6 mm (W and Fe) and 8.5 mm (W) flying in gas with different velocity was studied. The damaging threshold velocities of different balls were obtained. The investigation shows that the damage degree of balls depends on the material, velocity and the size of balls. The perforating ability of damaged balls through 6 mm thick steel targets was also studied.
