【Abstract】 An overview and classification of fault prediction techniques in machinery systems is presented. The importance of applied modeling approaches in fault forecast is introduced. Emphasis is focused on the advantages and disadvantages of the conventional forecasting models. The suitable range and applications of these models are also shown. Moreover, the trend of machinery fault prediction is discussed. For precise and reliable machinery fault detection, it is essential to use multivariable forecasting modes to describe the changes in several diagnostic indices. There are various trends in machinery fault development, so the fault quantification could be performed by means of combined forecast models.更多还原
