摘　　要：提出一种利用实弹射击数据对底排增程弹等效动力学参数进行拟合的方法,并利用拟合出的双参数对诸元进行求解,该方法无需对底排弹的底排装置和药柱的工作机理进行深入分析,也无需建立相关模型和参数估计,提高了工程实用性。试验结果表明,该方法的精度完全能满足炮兵射击的需要。Based on firing data, a fitting method of equivalent dynamic parameters for base bleed projectile is proposed in this paper, and then the ballistic data are solved using two fitted parameters. By this method it is not necessary to analyze the mechanism of bleed installation and bleed power or to establish the correlative model, improving the engineering practicability. The experimentation results show the precision of the method can meet the need of artillery shoot absolutely.
