Research And Development Of Test-system For High-pressure High-speed Hydraulic Motor Based On Labview

Most of the traditional Test-system for hydraulic motor are designed for general industrialhydraulic motor or construction machinery hydraulic motor，The object oriented high speed or lowspeed hydraulic motor. This can not satisfy the need of high-pressure and high-speed hydraulic motorperformance test. The topic aimed at the high pressure and high speed hydraulic motor testrequirements，developed a test bed and the test system that based on Labview. The system is able to35MPa high-pressure,12000r/min high speed of the hydraulic motor of the type test and routine testproject.In this paper, based on research and analysis of the status of the hydraulic testing technology athome and abroad and the hydraulic motor test stand, Firstly, for the high-pressure high-speedoperation of the hydraulic motor characteristics, that is, the highest35MPa,12000r/min, normal21MPa8800r/min the technical requirement, Conducted a detailed analysis of the test system,according to the results of the analysis，design，the overall design of the hydraulic system and the testsystem are completed. Secondly, elaborate hydraulic system principle of works, including oil sourceand the drag part、the oil temperature control part、the directional part、the loaded part. Then designa test system hardware components and the development of a software system based on Labview testbench test. in order to solve the test system of double input and double output control stabilityproblem，this paper designs a neural network based adaptive PID algorithm for the controlcharacteristics are optimized.Finally，test items of the hydraulic motor, such as run-in test、durability test、long-term cycle test、impulse performance test are done on the developed test-system，after experimental verified, itsfunctions and paraments meet the requirements of the design.
