摘要
在建立武器有限元模型与散布精度影响模型的基础上 ,构造了影响武器连发射击精度的多元目标函数 ,通过采用改变射击频率的方法 ,找出了连发武器射击频率与结构固有频率的合理匹配关系 。
Based on the finite element model and dispersion model, an objective function involving many variables affecting weapon's firing accuracy is established.By adjusting the rate of fire, reasonable matching relationship between an automatic weapon's firing rate and its inherent frequency of structure is established.The results have been verified by experiments and applied in the design of machine guns.
