基于截断正态分布的继电器多元维纳退化过程建模及可靠性评估
Modeling and Reliability Evaluation of Multivariate Wiener Degradation Process for Relays Based on Truncated Normal Distribution
摘要
Abstract
The reliability evaluation of relays is carried out on the basis of the multi-performance degradation model based on the degradation data of multi-performance parameters of relays.Several relay parameters are selected.An improved multivariate Wiener degradation model based on truncated normal distribution is established considering the actual statistical characteristics of the model parameters boundedness.Aiming at the established performance degradation model,a multi-stage model parameter estimation method is proposed.Taking reliability as the evaluation index of relay reliability,a reliability approximation calculation method based on Monte Carlo simulation is proposed.The accuracy and effectiveness of the method are verified by practical cases.关键词
