Simulation Analysis on Influence of Clearance Between Rockets and Launching Tubes on Initial Disturbance of Multiple Rocket Launcher

弹管间隙是影响火箭炮初始扰动的重要因素之一。依据某多管火箭炮的实际结构,建立了发射动力学模型。应用动力学显式有限元理论对模型进行了仿真计算,获得了不同弹管间隙条件下影响火箭炮初始挠动的相关参数。通过结果的对比分析,得到了火箭炮初始挠动随着弹管间隙变化的趋势,为火箭炮结构优化提供参考和借鉴。

The clearance between rockets and launching tubes is one of the most important factors which have the influence on the initial disturbances of rocket launcher.According to the actual structure of a kind of multiplerocket launcher,the launching dynamics model was established.Based on the explicit dynamics finite elementanalysis theory,the model was simulated and calculated to acquire related parameterswhich have influence on initial disturbances of rocket launcherunder the conditions of different rockets and launching tubes clearances.With the help of comparison and analysis of results,the trend of rocket launcherinitial disturbancesvaried with clearance between rockets and launching tubes was acquired.The results can provide reference for structure optimization of the rocket launcher.
