[Abstract]:As an important component of hydraulic system, the performance of hydraulic pump and motor has great influence on the performance of the whole hydraulic system, so it is necessary to study the hydraulic pump and motor test system. It is of great significance to protect the environment, and it can provide guidance for perfecting the structure principle of pump-motor test system. This paper summarizes the technical characteristics of different measurement and control systems, the working principle of different power recovery hydraulic pump, motor test system, and its advantages and disadvantages. Combined with the project, the overall scheme of the high-power hydraulic pump-horse test system is designed, the hydraulic principle of the system and the composition of the measurement and control system are explained, and the principle of the loading mode of the test system is studied. The influence of structural parameters of loading system on its loading performance is analyzed by Amesim modeling and simulation, and the influence of some parameters on the pressure loading performance of the system is analyzed by adding the control algorithm of loading system into the test system. According to the test requirements of the test bench, the upper computer software and the corresponding lower computer PLC program written in C # language are developed, and the basic functions of the test and control program are tested.
