摘要:结合超高分子量聚乙烯纤维增强塑料(UFRP)层合厚板抗高速侵彻的特点,将整个侵彻过程分为开坑
镦粗、剪切压缩和拉伸变形3个阶段。通过改进开坑懒粗阶段的计算方法和拉伸变形阶段的计算过程,基于能
量守恒原理建立UFRP层合厚板抗高速钝头弹侵彻的弹体侵彻深度和靶板弹道极限的计算模型,并给出相应的
计算流程图。通过采用该模型计算相关文献试验T况下的弹体侵彻深度和层合厚板弹道极限,发现计算值
文献试验结果均吻合较好。改进后的模型考虑了弹丸初速度对开坑繳粗阶段侵彻深度的影响,能够对高速钝
头弹侵UFRP层合厚板的弹体侵彻深度和层合厚板的弹道极限进行合理的预测,并可降低试验成本。

Abstract Due to the high penetration-resistance of thick ultra-high molecular weight polyethylene fiber
reinforced plastic (UFRP)laminates under high velocities, the whole penetration process is divided into
three phases: cratering & mushrooming phase, shearing& compression phase, and stretching deformation
phase. By altering the computation method for the cratering& mush rooming phase and the calculation pro
ces for the stretching deformation phase, an analytical model is established based on the energy conserva
tion principle to compute the penetration depth of projectiles as well as the ballistic limits of laminates in
the case of thick UFRP laminates being penetrated by high-velocity blunt-nosed projectiles. The corre-
sponding computation flow charts are also presented. Moreover, penetration depths of projectiles and ballis
tie limits of thick laminates under different test conditions are calculated with the model in a correlative or
der. It is seen that good agreements are obtained between the theoretically values and experimental results
Therefore, the improved model, which considers the projectile initial velocity effects on penetration dept
during the cratering mushrooming phase, can be employed to reasonably predict the penetration depths
Ind can reduce experimental costs, demonstrating both theoretical and engineering values
