Research on Life Prediction Method for GyroscopeBased on PACE

Gyroscopes are widely applied in weapon system and other high precision system. During the using course, the reliability and performance of gyroscope are influenced by environment and using condition. The performance of gyroscope degenerates periodically, and the remaining useful life (RUL) is payed close attention by engineers in order to monitor the whole systems steadily and safely during life-cycle. Traditionally, researchers used the reliability test and statistic method to estimate RUL. But it’s difficult to get enough samples in the test because the gyroscope cost much. In this paper, we mainly discussed the life prediction of gyroscopes, designed the accelerated life testing(ALT), and used Path Classification and Estimation(PACE) to predict the RUL of gyroscopes. In addition, we analyzed the theory of life prediction for gyroscopes, mainly about the relationship of gyroscope’s fault, nature element and useful life. Then the method is researched based on PACE method. At last, the prediction algorithms is illustrated by the practical accelerate life test data. The methods discussed in this paper was applied in a practical equipment maintenance support project, which can provide technical support for the product life prolong research work in the future.
