摘要
在某型转管炮射击实验中,机心运动发生卡滞、机心滚轮与炮箱凸轮曲线槽以及机心与星形体导轨之间的磨损较严重,因此开展对转管炮机心结构的研究,分析机心滚轮与炮箱凸轮曲线槽之间正压力和机心结构的变化关系。根据达朗贝尔原理,得到机心动平衡方程,利用Matlab得到机心径向宽度、导轨理想作用点高度、导轨倾角的参数采样点矩阵,分析机心结构参数与正压力之间的关系。结果表明:机心径向宽度和导轨理想作用点高度值越大,正压力越小;导轨倾角的改变对正压力的影响随着射速的提高而逐渐增大,当机心选取较大的径向尺寸和导轨理想作用点高度时,导轨倾角越大越好,反之,水平最好。
In the experiment of a certain type of Gatling gun,the movement of Bolt Carrier is stuck,and the cam groove and guide rail wear seriously.The relationship between the bolt carrier and the positive pressure of roller and the cam groove was analyzed.According to the principle of D’Alembert,the dynamic balance equation was obtained.The radial width of bolt carrier,the ideal point height of the guide rail and the inclination angle of the guide rail were parameterized by Matlab.The relationship between the structural parameters of bolt carrier and the positive pressure was analyzed by using the surf function.The results show that the larger the radial width of the bolt carrier,the height of the guide rail,and the smaller the positive pressure.The influence of the inclination on the positive pressure gradually increases with the increase of the rate of fire.
