In order to investigate the influence of a strong vibration environment on the working performance of two way cartridge valves, the structure model and simulation model of the cartridge valve in a vibration environment are established using AMESim software. Influence laws of the vibration condition and the structural parameters of the cartridge valve to its dynamic characteristics are also analyzed separately. The results show that foundation vibrations can cause the cartridge valve flow and open height to fluctuate. The degree of fluctuation of the open height in the steady state increases linearly with the amplitude of the foundation vibration, and is significant when the vibration frequency is over 20Hz. Furthermore, a smaller damping hole diameter can increase the time of the flow raise to the maximum, but the hydraulic oil flow through the valve will be smoother; the fluctuation degree of the open height increases correspondingly with spool quality when the cartridge valve is in the opening state; changing the cartridge valve area can reduce the flow fluctuation; and finally, increasing spring stiffness can also reduce the flow fluctuation, but reduce the flow through the valve.
