【摘要】 描述了球形破片侵彻有限厚靶板的侵彻过程，建立了反映侵彻速度和侵彻深度间关系的分析模型．依据空穴膨胀理论计算侵彻阻力，依据Ａ－Ｂ模型将侵彻过程进行分解，并给出了各过程的侵彻方程，基于该模型研究了程序代码，以钨球对钢板、钨球对铝板分别模拟．球形破片对靶板进行了实例计算，并和试验结果进行了比较．更多还原

【Abstract】 In this paper, the process of spherical fragment penetrating limitedthickhess targets is described, and the analysis model which shows the relation of penetration speed and penetration depth is built. Penetration force can be calculted according to the theory of dynamic spherical cavity expansion, and the whole penetrtion is delimited on the basis of AB model, and penetration funtions in every process are given. Compute code based on the model is made. We take tungsten sphere to stell target and aluminum target as examples to make calculations in our models. To verify our models, we conducted penetration experiments, and compared the data of experiments with the results of calculation.更多还原
