Abstract Hydraulic motor as power components and actuators is the heart of the hydraulic system,its performance directly influences the whole performance of the hydraulic system. So precise hydraulic motor performance test has a very important significance. Hydraulic motor performance test is an important means to identify product quality,improve the structure design,improve the level of technology,ensure system performance and promote product upgrades.
The design involved in this paper mainly discusses how to test hydraulic the eligibility of hydraulic motors by measuring displacement, flow, volumetric efficiency of the cycloid hydraulic motors with given external conditions.
In this paper,we design the hydraulic system bench of the cycloid hydraulic motor;and calculate the related parameters,map the cycloid hydraulic motor experiment system schematic diagram.We design the cycloid hydraulic motor test rig measurement and control system as a whole,selection the components , design the hardware circuit,so we can finish the national standard of the test content and meet the corresponding test accuracy.We use simulation software to simulate and analyze the stability of cycloid hydraulic motor.For the control system software development of cycloid hydraulic motor test rig measurement, We use VB.NET as the development software to Achieve the functional of the test board to control the data acquisition and processing with its easy to use visual programming tools, programming mechanism based on the event-driven, powerful and flexible numerical calculation, graphic capability and database programming.
Keywords: Cycloid hydraulic motor test rig; hydraulic system; measurement and control system
