摘要(Abstract):

针对现代战场上对多层介质破坏难的问题,提出多层介质结构模型来研究多层介质的破坏机理。通过理论分析、数值模拟及试验方法研究了介质性质、起爆方式、炸深对多层介质破坏的影响。结果表明:介质波阻抗越接近,能量传递利用率越高;下端起爆方式更有利于多层介质破坏作用;多层介质存在一个最佳炸深。研究结果对提高多层介质目标破坏作用有一定指导意义。
In order to solve the problem of multi-layered medium destruction in modern battlefields, we propose a multi-layered medium structure model to study the failure mechanism. Through the use of theoretical analysis, numerical simulation, and experimental methods, we have studied the effect of multiple factors, such as the properties of the medium, the method of initiation, and the depth of explosion, on the failure of multilayered medium. The results show that the closer of dielectric wave impedance, the more efficient of energy transfer,and the lower-end initiation method is more conducive to destruct multilayer medium, and there is an optimal depth of explosion for multi-layer media. The research results have certain guiding significance for improving the destruction effect of multilayer dielectric targets.
