Hydraulic safety valves play an extremely important role in the hydraulic system design of aircraft. However, if the design and select of safety valves are not reasonable, it will cause much trouble to the hydraulic systems, and the most common and important one is the system vibration and whistles when the safety valves open, especially in the large high pressure hydraulic systems. Initial research pointed that these system vibration and whistles is related to the structure design of safety valves. In this paper, based on the indicated flow rate, open/close pressure and full open pressure, a new type of safety valve with small volume and weight has been designed, and then a physical simulation model based on the structure design has been established and simulated by AMESim and the structure of the valve has been optimized based on the simulation and analysis results of dynamic response of the valve.
