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1 600~1 800 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。
Some experiments of impacting semi-infinite target perpendicularly were carried out by the triangular and quadrangular cross-section penetrators, at length-diameter 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 able to anslyze the penetration characteristic of non-circular rods impacting semi-finite target commendably.
