摘要
In order to detect the nonlinear characteristics (flow hysteresis) of aviation fuel valves and to improve the accuracy and efficiency of fuel valve performance test, a computer aided fuel valve automatic test system is designed. The test system mainly consists of industrial control computer, data acquisition card, signal conditioning circuit and test software developed on the LabVIEW virtual instrument platform. Independent adjustable constant current source module with high drive capacity is designed to output stable current for the coil of fuel valve, so as to realize closed-loop control. Besides, the method of grouping test is taken for actual testing and debugging, which help find out potential problems and improve the development process of the test system. The experiment results show that the system not only has an accurate and efficient test result, but also has the steady ability to detect the flow hysteresis of aviation fuel valve.
