摘要:
为研究贫铀合金与钨合金破片毁伤性能的差异,采用ANSYS/LS-DYNA有限元软件,运用Lagrange算法,以侵彻速度为950和1 000 m/s的球形和柱形破片侵彻靶板为研究对象,对比分析了贫铀合金破片和钨合金破片侵彻钢靶的侵彻过程和速度特性,并采用13.1 mm的弹道枪对模拟结果进行了验证。结果表明,贫铀和钨合金破片在其侵彻过程中,贫铀合金表现出的自锐特性可使破片头部变尖,侵彻能力增强。当破片形状和质量相同且侵彻初速为1 000 m/s时,柱形贫铀合金破片的剩余侵彻动能是钨合金破片的1.3倍,球形贫铀合金破片剩余的侵彻动能是钨合金破片的2.3倍;当初速相同、形状不同时,球形贫铀合金破片剩余速度的最大值是柱形破片的2.1倍,球形钨合金破片剩余速度的最大值是柱形破片的1.6倍,因此球形贫铀合金破片的侵彻能力最优。通过试验结果与模拟结果的对比,得到模拟计算的最大误差为8.8%,验证了模拟计算的正确性。
Abstract:
To study the difference of the damage performance of depleted uranium (DU) alloy and tungsten alloy fragments, using finite element software ANSYS/LS-DYNA and lagrange algorithm, taking the spherical and cylindrical fragment penetration target plate with the penetration velocities of 950 and 1 000 m/s as the research object, the penetration process and velocity characteristics of the steel target plates penetrated by DU alloy fragment and tungsten alloy fragment were compared and analyzed, and the simulation results were verified by 13.1 mm ballistic gun. The results show that in the penetration process of DU alloy fragment and tungsten alloy fragment, the self-sharp properties revealing by DU alloy fragments can make the head of the fragment tip become sharp and the penetration ability enhance. When the shape and mass of fragments are same and the initial penetration velocity is 1 000 m/s, the residual penetration kinetic energy of cylindrical DU alloy fragment is 1.3 times of tungsten alloy fragment,and the residual penetration kinetic energy of spherical DU alloy fragment is 2.3 times of tungsten alloy fragment. When the initial velocity is equal but the the shape is different, the maximum value of residual velocity of spherical DU alloy fragment is 2.1 times of cylindrical fragment, the maximum value of residual velocity of spherical tungsten alloy fragment is 1.6 times of cylindrical fragment, so the penetration ability of spherical DU fragment is optimal. Through comparing the experimental results with simulated ones, the calculated maximum error is 8.8%, which verified the correctness of simulated calculation.
