本文对舰载导弹垂直发射装置中的燃气流周期性振荡特性进行了分析与实验测量，对装置产生的响应特性也进行了实验研究和有限元分析。实验测量结果与理论计算在规律上有定性的一致
This paper analyzes and experimentally measures the periodic oscillation of the gas flow in a vertical launch device of a shipborne missile. The response characteristics of the device are also experimentally studied and analyzed by finite element analysis. Experimental results and theoretical calculations are qualitatively consistent with the law
