| Abstract: | According to the working principle of the electro-hydraulic proportional valve,its mathematical model was established.MATLAB was used to simulate its dynamic characteristic and stability.It is shown the valve has a good response speed and stability.Through a signal test system,the follow performance of the valve in hoist braking hydraulic system test stand was researched.The result shows that the valve has a good follow performance for oil pressure,while the pressure overshoot,vibration and shock caused by the step change of pressure control are avoided.So the control performance of the hydraulic system is improved. |
