Dynamic Analysis And Simulation On Hydraulic Control System Of The Double 130 Naval Gun

The naval gun is a widespread weapon of modern various surface naval ships and it is the valid weapon which provides firepower support for the sea of the opposite shore and strikes the low threat target at sea. Along with the development of ammunition technique, the naval gun is playing the more and more important role in the aerial defense and antimissile function. There, international communities, especially the United States and Russia are stepping up to develop new types of naval gun or improving current naval gun to adapt for the demand of the sea high technique limited war of 21 century.This topic is mainly studying the electro-hydraulic servo-control system of the naval gun, which is made up of electric signal processing and hydraulic power output. Because its electricity monitors diverse it can constitute closed control system with various physical quantities. The electro-hydraulic servo-control system has the advantages of electrical system and hydraulic system. It has the advantages of high control accuracy, fast response velocity, smooth signal processing, large output power, compact structure, light weight and so on.This system is made up of the electric control system and the hydraulic transmission system. The electric control system mainly delivers, examines, enlarges and compensates the signal. In the hydraulic control system, the electro-hydraulic servo-valve changes the electric voltage signal of the error margine control of the enlarger's output to hydraulic signal. After being enlarged the signal is outputted by hydraulic monitor to arouse the naval gun sport, which makes the naval gun complete full-automatic or the half following the mission of target automatically. The hydraulic control system's quality of characteristic is one of the most important factors which influenses the blast-off rate, shoot accuracy and the stability of the naval gun.By analyzing the principle of the hydraulic control system of the naval gun, we get several basic circuits and we simply introduce the principle of them. Then the topic analyzed the main circuit's dynamic quality of the electro-hydraulic servo-control system of the naval gun, established its model and simulated it. So we knew the dynamic state characteristic and the working stability of the electro-hydraulic control system. By analyzing the math model's transfer function of the circuit's main link, the topic established the dynamic simulation model according to the Simulink modules. After putting the parameters of the hydraulic control system into the Simulink modules and simulating them, the topic get the digital simulation result of the system. So the topic completed the simulation of the static and the dynamic state characteristic of the naval gun which provided theories for the optimum design for the hydraulic control system of the naval gun.The topic finally discussed several factors which influence hydraulic control system's dynamic state characteristic, come to a summary about the topic and made an outlook to the further research.
