混凝土靶体中侵彻与贯穿的过载估算方法

An Estimative Method of Deceleration-time of Penetration and Perforation for Concrete Target

根据得到的侵彻近区速度场新的表征和侵彻过程中受到的阻力表达式,提出了弹体在混凝土靶体中侵彻与贯穿的过载计算模型,该模型具有宽广的比例换算关系。计算得到了侵彻与贯穿时弹体的过载时程曲线。通过与国内外实验结果的对比分析,验证了文中方法的可信性。

The deceleration of projectile during penetrating and perforating to concrete target was studied. Based on new velocity and the resistance expressions of projectile, the prediction model of deceleration was established during penetrating and perforating to concrete target. A diameter scale conversion is included in the model. The curves of deceleration versus time were achieved with the model. The comparative analysis between the model and experimental data demonstrates that the prediction is credible.
