某步枪弹侵彻明胶杀伤特性仿真研究
|
摘要
基于ANSYS/LS-DYNA高度非线性动力学仿真软件,研究某步枪弹侵彻明胶仿真技术,仿真结果与实际测试结果吻合,各时刻位移点误差均小于10%,在此基础上分析不同攻角以及不同射程处步枪弹在明胶内运动特性,结果表明:攻角、射程均与杀伤效果呈二次多项式关系。攻角小于1°时,对弹头能量传递量的影响较为敏感; 400 m射程内,射程与能量传递量基本呈线性关系。
Based on ANSYS/LS-DYNAof highly nonlinear dynamics simulation software, it studied simulation technology of rifle bullet penetrating gelatin. The simulation results are consistent with with the test results,and the displacement error is less than 10%,thenwe analyzed rifle bullet movement properties in the gelatin including different attack Angle and different range. The results show that: the attack angle,range and wound effect show a quadratic polynomial relation. When attack angle is less than 1°,the energy transfer is sensitive; Within the range of 400 m,the relation between the range and energy transfer is basically linear.
