Abstract
The life prediction and preventive maintenance have been long the problem concerned. Based on the probabilistic calculation method of high temperature components, the relation between life and reliability of high temperature components was obtained. This result would supply the technical support with the preventive maintenance strategy. The preventive maintenance theory was used in the study of optimum preventive maintenance strategy and maintenance period for high temperature components. The optimum maintenance period problem under age based maintenance and periodic maintenance has been solved based on the least cost principle. The results showed that the strategy of age based maintenance is reasonable for preventive maintenance of high temperature components.
