固支圆板在动爆冲击波作用下的动力响应

为研究装药运行速度对爆炸冲击波毁伤威力的影响，利用Autodyn软件对动爆冲击波作用下装甲钢圆形靶板的变形进行了数值仿真，建立了动爆冲击波作用下圆形靶板中心挠度的理论计算模型，并将仿真结果与理论计算结果进行对比.研究结果表明:装药运行速度极大地提高了沿装药速度方向爆炸冲击波的超压峰值，加快了沿装药速度方向爆炸冲击波的传播速度；建立的理论计算模型能准确计算周围固定圆形靶板在动爆冲击波作用下的中心挠度值，具有普遍适应性. 

Dynamic Response of Fixed Circular Plate Subjected to Dynamic Explosion Shock Wave

In order to study the influence of charge speed on the damage power of explosion shock wave, Autodyn software was used to simulate the deformation of armored steel circular target plate under dynamic explosion shock wave, the theoretical calculation model of central deflection of armored steel circular target plate under dynamic explosion shock wave was established, and the simulation results were compared with the theoretical calculation results. The results show that the overpressure peak of the explosion shock wave along the direction of charge velocity is greatly increased and the propagation speed of the explosion shock wave along the direction of charge velocity is accelerated. The theoretical calculation model can accurately calculate the central deflection of the fixed circular target plate under dynamic explosion shock wave, and has universal applicability.
