摘要:
在已求得弹性枪架等效刚度的基础上 ,以枪架托架上端部作为特征点 ,假设枪架的动变形与静变形成正比 ,利用能量等效原理 ,进一步分析弹性枪架的等效质量 ,结果可用于获得自振时全枪的固有频率或用于求解射击时全枪的动力响应。
Abstract:
Based on the equivalent stif fness of elast ic t ripod mount, w hich has been obtained in another paper, this paper takes the jointing posit ion of gun and its mount as the characterist ic point and assumes that the dy namic deflection of the t ripod mount is proport ional to the static one. T hen the equivalent mass of the elastic t ripod mount is analyzed by using the equivalent theorem of energy. The result s may be used to obtain the eigen-frequency and dynamic response of the gun.
