- Abstract:
- The fitting of the statistical distribution of failure data is used to estimate the remaining useful life of infant
incubator fan for providing guidance for preventive maintenance. After that the failure data of the fan is preprocessed, the
prior knowledge is used to model the failure data with Weibull distribution, and then the maximum likelihood method is used
to estimate the model parameters and obtain the life distribution of the fan. Finally, the established model is applied to
estimate the remaining useful life of the fan. The results reveal that the proposed method can be used to estimate the
remaining use life of components, thereby guiding the predictive maintenance of medical equipments.
