摘　　要：为研究潜射导弹发动机在弹射筒内弹射过程的环境适应性,研制了一种模拟弹射筒内动态压力环境的气体冲击试验系统。通过试验系统的数学模型仿真分析,匹配合适的蓄压罐容积、管道通径、冲击室容积和排气孔,能够在定容积冲击室内模拟导弹弹射筒内的气体压强历程曲线。提出的固体发动机浮动环安装方案,能够有效提高气体冲击曲线模拟精度。建立的气体冲击试验的评价指标体系,可用于评估压强历程曲线的模拟有效性。试验结果表明,气体冲击试验方法能够满足发动机弹射筒内环境适应性试验需求,并且试验成本低、冲击曲线重复性好,曲线峰值压强、峰值时刻便于调节。In order to study the environmental adaptability of motor during the launching process of submarine-launched mis-siles,a gas impact test system was developed to simulate the dynamic pressure environment in the launching tube.Through mathe-matical model simulation analysis of the test system,and matching the appropriate volume of pressure storage chamber and impact chamber,tube diameter,exhaust hole,the gas pressure history curve can be simulated in the constant volume impact chamber.The proposed floating ring installation scheme of solid rocket motor can effectively improve the simulation accuracy of gas impact curve.An evaluation index system of gas impact test was established for assessing the simulation validity of dynamic pressure curve.The test results show that the gas impact test method could meet the requirements of environmental adaptability,low cost,good repeat-ability of impact curve and peak pressure and peak time of impact curve easy to adjust.
