A set of hydraulic test system was designed and built to complete the performance test for pumps. Next, the simulation model of the system was built in the hydraulic simulation software AMESim, and the models of tested pump, relief valves and check valves were built by HCD library. According to National Standard JB/T 9714-1999, the necessary test items were simulated and the dynamic responses of the test system were analyzed. Simulation results show that the test system can exactly reflect the performance parameters of tested pump and meet the demand of hydraulic pump performance test. Finally, corresponding test bed was built according to the test system and verified the above simulation results. Experimental results were consistent with simulation results, which proves the feasibility of the test system.
