The Design of Comprehensive CAT Test Rig for Electro-Hydraulic Servo Valve
By comparing the limitation of traditional test rig for electro-hydraulic servo valve and the advantages of CAT test rig for electro-hydraulic servo valve, this paper demonstrates an overall CAT test rig design including hydraulic system design and test software design. This work applies virtual instrument technology based on LabVIEW and adopts OPC standard to realize real-time communication between computer and PLC. Eventually as a case study, a test example of a well-functional servo valve is presented to show the validity and accuracy of the test rig.
