The hydraulic valve affects the normal operation of the hydraulic system to a large extent. A comprehensive test bench for performing multiple performance tests on various hydraulic valves is designed to test the performance index of the hydraulic valve. In order to realize the automation of the test bench, to improve the measurement accuracy and to reduce the human factors, the hydraulic valve performance test software was developed based on the LabVIEW platform by using the powerful data processing function of computer. And the NI acquisition card was used as the middle end of signal connection for signal output control and data acquisition and processing. By introducing the idea of modularization design and two times development of test software, the required functions are processed in a modular way, which greatly shortens the development cycle of test software and realizes the test bench automatic regulating system pressure and flow rate to meet the performance test requirements, and can realize collecting high precision test data, drawing the characteristic curve, automatic unloading after the test, data storage and printing test reports, and etc.
