| 摘 要： | 针对长径比为20，截面形状分别为三角形和四边形的两种异型杆，在1600～1800 m/s速度范围内，开展了其垂直侵彻半无限靶板的试验研究和模型分析，在模型中考虑了弹杆横截面对异型杆侵彻均质靶板的影响。理论与试验结果的对比表明，该理论模型可以较好地分析异型杆垂直侵彻半无限靶板的侵彻特性。

| Abstract: | Some experiments of impacting semi-infinite target perpendicularly were carried out by the triangular and quadrangular cross-section penetrators,at lengthdiameter ratios of 20,impacting velocity of 1 600 m/s to 1 800 m/s.After that,some interrelated analytical models were made.In the models,how the cross-section of rods affect the performance of the non-circular rods penetrating homogeneous target was discussed.Compared with the foregoing experimental outcome,the theoretical analysis result is proved to be ... |
