Reliability Analysis of Nuclear Power CNC Wheel Groove Milling Machine Based on Gray Theory

Abstract:

The reliability data of nuclear power CNC wheel groove milling machine is so few that the reliability can not be predicted by traditional reliability prediction method;or the reliability prediction error is large. A reliability prediction method of nuclear power CNC wheel groove milling machine based on the gray theory is proposed in this paper. Establishing the reliability model of gray theory, the reliability of machine subsystem is determined. Then the relationship between the corresponding average fault-free time and system reliability is realized. The gray comprehensive correlation between theoretical output of the model and the actual system reliability is established, the overall reliability of the nuclear power CNC wheel groove milling machine is determined. For system reliability analysis and system maintenance decision research puts forward a new thinking path, have a good applied foreground. Key words: the nuclear power CNC wheel groove milling machine; gray theory; average fault-free time; system reliability; reliability analysis.
