Design of automatic hydraulic test bench based on LabVIEW

This paper introduces virtual instruments technology and develops a hydraulic test bench based on it. This test bench realizes the function of data acquisition, real-time display, output configuration, pressure adjustment, test data saving and report generation. Architecture of the test bench is introduced and its LabVIEW-based software design method is illustrated in detail. Compared to traditional systems, this test bench has many advantages like fast designing, easily expanding and automatic data judgment.
