以平均误差、残差平方和以及相关系数为主要参考指标,以NASA/MSFC SDIF的超高速侵彻试验数据为样本,对11种薄靶超高速撞击成孔直径经验公式进行了优选对比分析,给出了在较宽速度范围内的经验公式。
Taking the average error, residual square sum and correlation coefficient as the main reference indices, the empirical formulas of 11 kinds of thin-gauge superhigh-speed impact piercings diameters were compared and analyzed based on the NASA / MSFC SDIF ultra-high-velocity penetration test data. The empirical formula is given over a wide range of speeds.
