射流作用条件对重型反应装甲干扰时长的影响

为研究聚能战斗部倾角与炸高等射流作用条件因素对重型反应装甲干扰作用时长影响，采用数值模拟与理论计算相结合的方法建立了射流作用条件影响重型反应装甲干扰时长计算模型，获得了不同倾角炸高对爆炸反应装甲飞散特性及干扰场作用时长的影响规律. 数值模拟结果表明，倾角炸高对反应装甲飞板飞散行为和干扰场作用时间影响显著；飞板飞散速度、加速度峰值随倾角增大而下降；随着炸高增大，峰值先增大后减小. 炸高较小时(2d_c)，干扰时间随着倾角增大而增大；炸高较大时，干扰时间随着倾角增大而减小. 数值模拟结果与理论计算结果吻合较好. 

Research on the Effect of Jet Action Conditions on Interference Duration of Heavy Reactive Armor

In order to study the effect of jet action condition factors such as inclination angle and standoff of the shaped warhead on the interference duration of heavy reactive armor, a calculation model of jet action conditions affecting the interference duration of the heavy reactive armor was established by a combination of numerical simulation and theoretical calculation. The law of the influence of different inclination angles on the flying characteristics of the explosive reaction armor and the duration of the interference field was obtained. Numerical simulation results show that the blast height of the inclination angle has a significant effect on the flying behavior of the reactive armor flying plate and the action time of the interference field; the flying speed and the peak acceleration of the flying plate decrease with the increase of the inclination angle; as the blast height increases, the peak value first increases and then decreases. When the explosion height is small (2d_c), the interference time increases with the increase of the inclination angle; when the explosion height is great, the interference time decreases with the increase of the inclination angle. The numerical simulation results and the theoretical calculation results match well.
