一定厚度混凝土靶极限贯穿速度分析

摘要

由于进行靶场试验不能准确测得有限厚度混凝土靶的极限贯穿速度,针对这一问题,利用ANSYS/LS-DYNA有限元仿真软件对100 mm穿甲爆破弹侵彻1 000 mm厚混凝土靶板的过程进行数值模拟,然后使用经验公式计算出该弹靶模型的极限贯穿速度,并与数值模拟结果进行比较,从而验证数值模拟结果的正确性.%Because the ultimate penetration velocity of concrete target with finite thickness can not be accurately measured by shooting range test, in view of this problem, this paper uses ANSYS/LS-DYNA finite element simulation software to simulate the penetration process of 100 mm armour-piercing blasting projectile into 1000 mm thick concrete target plate, and then calculates the model of the projectile and target by using empirical formula.The ultimate penetration velocity is compared with the numerical simulation results to verify the correctness of the numerical simulation results.
