研究了一种计算非控榴弹战斗部破片质量分布规律的新算法。从壳体膨胀过程开始分析 ,结合到壳体尺寸 ,材料性质和临界破坏能 ,探讨了确定 MOTT理论常数的方法 ,计算结果与试验结果对比在一定的误差范围内 ,表明该方法避免了以前确定计算中的不确定性 ,结果表明此方法是一种预测破片质量分布规律参数的可行途径。

A new method of the calculation of nature-fragment mass distribution for small diameter howitzer projectile. From the driven shell expanding to the applications of shell's dimensions, material properties and the critical fragmentation energy, the method of determining the constance in MOTT theory equations has been discussed. The discrepancy between the new calculations and test results is within a better intolerance. It avoids the incertitude using the experience MOTT equations. All the results show that the way in this paper to calculating the fragment mass distribution of small howitzer projectile is quite applicable in designation.
