| Abstract: | Residual life prediction is a critical and difficult problem in condition-based maintenance decision-making.To deal with the problem of limited practical data and inaccurate estimation of initial parameters in maintenance practice,a residual life prediction method for gearbox based on stochastic filtering （SF）is proposed.In this method,recursive expectation maximization （REM） algorithm is introduced to update the parameters,and a maximum likelihood estimation method is designed to update the unknown parameters.Finally,the validity and practicability of the model are validated by an example. |
