doi:10.3901/JME.2020.04.218

Abstract

Abstract: There is not filtration design of actuators of (Five-hundred-meter aperture spherical radio telescope, FAST). With the working time increasing, most of oil contamination level of hydraulic actuators of FAST is exceed allowable values, and the reliability and lifetime of actuators are cut down. To solve the problem, the principle of dynamic balance of oil filtration is proposed. The mathematical model of contamination control for hydraulic system is established, and the solution of hung outside filtration system for hydraulic actuators is designed. The model is simulated by Matlab. The results show that the dynamic balance state of actuator can be attained by 10 times working after the hung outside filtration system installed, and the oil of NAS6 can be achieved at the same time. The test of prototypes is completed, and the results of simulation and test agree with each other very well. The effectively of the solution for actuators is proved to improve the grade of hydraulic oil, and the mathematical model is proved to be correct. An effective solution is provided to solve the problem of actuator of FAST by the method of combination theoretical analysis and test. Meanwhile, it can be used as the reference for similar research of hydraulic pollution control.

Key words: actuators, dynamic balance, mathematical model, contamination control of oil, reliability and lifetime
