In order to solve the problem of dynamic test and achieve the performance test of large flow relief valve, an accumulator fast loading dynamic test system was designed and developed. The AMESim model and Simulink simulation control model were established by using AMESim and MATLAB/Simulink softwares in allusion to the system, and a combined simulation interface in the AMESim model was set up. Combined simulation and research of the large flow relief valve dynamic test system were done by using the S-function in the Simulink module, six control signal curves of system and the pressure of booster cylinder high pressure chamber, dynamic pressure and dynamic flow of the measured large flow relief valve curves and result data were obtained, and the results were compared with the experimental results. It is provided important evidences for studying dynamic properties and operational reliability of large flow relief valve.
