摘要: 为减少转管炮身管寿命试验的用弹量,研究用非满管代替满管进行转管炮身管寿命试验的技术。建立炮口振动位移计算方程,利用高阶傅里叶级数拟合炮膛合力,获得炮膛合力的频域函数;利用模态实验获得了转管炮的模态参数,构建转管炮起落部分的频响函数;利用频响函数计算了转管炮在满管射击、非满管射击方式下的炮口振动位移。以满管射击、非满管射击方式下炮口振动位移的一致性为原则,确定身管寿命试验方案。通过试验验证了满管射击、满非管射击方式下的身管寿命试验结果具有一致性,从而获得用弹量较少的身管寿命试验方法,节省了试验的弹药消耗。

Abstract: The technology of substituting full charge loading with non-full charge loading is researched to decrease the ammunition consumption in the barrel life test of revolving barrel cannon. The computing equations of muzzle vibration displacement are established. High-order Fourier series is used to fit the resultant force in bore, and then the frequency equations of resultant force are established. The modal parameters of cannon are obtained by model measuring and analysis, and a frequency response equation of the cannon elevating part is established. The frequency response equation is used to calculate the muzzle vibration displacements in the way of non-full charge loading and full charge loading. The differences among these muzzle vibration displacements are compared. Based on the law that the muzzle vibration displacements of non-full charge loading and full charge loading are consistent, the barrel life test scheme is confirmed. In verification experiment, the barrel life’s consistency is proved. The barrel life test method of less amount ammunition is designed to decrease the ammunition consumption in test. Key
