摘要：

为研究液压油质特性变化对火箭炮高低调炮的影响，以某火箭炮高低随动系统为研究对象，基于MSC.ADAMS、EASY5仿真软件建立高低随动装置机电液耦合动力学模型，并通过对比试验与仿真结果验证模型的可信性。在此基础上，重点分析液压油温与含气量对火箭炮高低调炮的影响，同时针对液压油污染导致的过滤器堵塞故障进行仿真分析。结果表明：液压油温与含气量对火箭炮高低调炮的影响不能忽略，过滤器堵塞故障隐蔽性较强不易察觉，通过改变液压油质特性进行仿真可以获得较完善的知识与样本，为火箭炮液压系统故障诊断与维修保障提供参考。

Abstract: In order to study the influence of the change of hydraulic oil quality on the launcher's high and low level gun movement, a rocket-gun rocket high-low servo system was taken as the research object. Based on the MSC. ADAMS and EASY5 simulation software, the electromechanical-hydraulic coupling dynamic model of the high and low servo device was established. The comparison test and simulation results verify the credibility of the model. On this basis, the influence of hydraulic oil temperature and gas content on the action of rocket launchers was analyzed. At the same time, the filter blocking failure caused by hydraulic oil pollution was simulated and analyzed. The results show that the influence of hydraulic oil temperature and gas content on the level of rocket launcher can't be neglected, and the concealed fault of filter blocking is not easy to be noticed. By changing the characteristics of hydraulic oil, simulation can obtain more complete knowledge and samples, and provides a reference for the fault diagnosis and maintenance support of the rocket hydraulic system.
