| 摘 要： | 对钨合金长杆弹垂直侵彻横向运动钢板的偏转角变化规律进行了理论及仿真研究。采用刚体力学理论推导了刚体长杆弹侵彻横向运动钢板的偏转角公式。利用ANSYS/LS-DYNA有限元软件对RIGID及STEINBERG两种材料模型长杆弹垂直侵彻横向运动JOHNSON-COOK模型钢板进行了仿真,根据长杆弹头部和尾部横向相对运动规律,得到了长杆弹的偏转规律。仿真结果表明:板的横向运动速度越大,长杆弹偏转角越大,且偏转角在整个侵彻过程中一直保持增大的趋势。

| Abstract: | The theory and simulation of the change rules of deflection of the tungsten alloy long-rod projectile that vertically penetrates into traverse moving steel plate are explored. The deflection equation of the steel long-rod projectile penetrating into traverse moving steel plate is deduced with the geostatic. The RIGID and STEINBERG mode long-rod projectile vertically penetrating into traverse moving JOHNSON-COOK mode steel plate are simulated with ANSYS/LS-DYNA finite element software. According to the trave... |
