Reliability Evaluation of Bearings in theIntelligent Robot for Changing the Hobwithout Failure Data

doi:10.3901/JME.2019.02.186

Abstract

Abstract: It is difficult to obtain the point estimation and confidence interval estimation of the parameters simultaneously by using a single model in the current reliability evaluation method of zero-failure data. If different methods are used for point estimation and interval estimation, the consistency of the results will be caused. In order to solve this problem, the reliability analysis of rolling bearings at rotating joints in an intelligent tool changing robot system without failure data is carried out, and a new reliability evaluation model based on zero-failure data is proposed. The E-Bayes method is adopted by the new model to derive the probability distribution curve of product life, and then the point estimation of product reliability is obtained. Then, the parameter Bootstrap method is used to re-extract new samples from the life probability distribution, and the interval estimation of product reliability is obtained from the new samples. The point estimation and interval estimation of product reliability are obtained simultaneously without reducing the credibility of the result. The case analysis shows that the new model not only meets the requirements ofreliability assessment, but also improves the accuracy of reliability interval estimation under Weibull distribution. The proposed model is validated to be feasible in the process of reliability evaluation of zero-failure data, and it is also convenient for engineering application.
