| 摘 要： | 对伸出式侵彻体垂直侵彻半无限靶板的物理过程进行了描述,分析了侵彻过程中一些重要参量的变化规律,并对此过程进行了三维数值模拟,模拟结果与试验结果有较好的一致性;与具有相同质量相同外径的基准杆进行了比较,结果表明,在火炮速度范围内,伸出式侵彻体相对基准杆有较大的穿深增益,而且这种穿深增益随着撞击速度的增加而逐渐增加.

| Abstract: | The physical process of extended penetrator penetrating perpendicularly into semiinfinite target was described. Variation of some important parameters during penetration were analyzed. Three dimensional numerical simulation of the penetration process was carried out. The results agree with the experiments well. Compared to the baseline rod with the same mass and outer diameter, the results show that the extending penetrator is much better than the baseline rod in depth of penetration, and the merit raises with the increase of the impacting velocity. |
