Stability Modeling and Simulation of Hydraulic Cartridge Sequence Control

Due to the ignorance of the instability of hydraulic cartridge sequence valve and the resulting accidents, this paper presents stability analysis of the cartridge sequence valve. First, the operation of the valve was illustrated, then a theoretical analysis was given, and simulation under AMESim environment was carried out, hence the variations of the control variables during the dynamic process were discussed in detail, finally, experiments were done which validated the simulation results.
