Movement Characteristics Analysis of Rotary Chamber Mechanism of a Gun Automatic Mechanism

为进一步研究某导气式火炮转膛机构的运动特征,以该转膛自动机为研究对象,运用火炮经典动力学理论,建立了自动机两自由度数学模型。在VisualBasic语言环境下编写程序,采用龙格-库塔(R-K)法进行求解,仿真得到了自动机各构件运动规律曲线。根据得出的各组数据,分析了滑板曲线槽对转膛机构的影响,并对导气室结构参数进行了优化,确定了导气孔的最优值和最小可工作值。这些研究结果可为该自动机的后续设计与结构优化提供理论依据。

In order to analyze the movement characteristics of rotary chamber mechanism of a gas-operated gun,the revolver automatic gun was taken as the object of study and the 2D mathematics model of the gun was established based on the theories of classical dynamics.Using the Visual Basic software environment,the movement law of structure member was obtained with Runge-Kutta algorithm.According to simulation data,the influence of slide curve trough on revolver chamber was analyzed,the optimum and the minimum numerical value of gas vent were acquired by optimizing the parameters of the gas chamber structure.Further design and structural optimization of the automatic gun can be guided by these results.
