Research on Reliable Running Time of Motorized Spindle Based on Health Indicator

EasyChair Preprint 3630

Abstract

Motorized spindle is one of the key components of CNC machine tools,it aims to predict the future reliable working time of the equipment, provide support for maintenance decisions. It is of great significance to reduce maintenance support costs and improve the stability of the equipment .This paper proposed a model to estimate the reliable running time based on health indicator, which is used as an index to monitor the health status of the motorized spindle, and the health index model is established based on single feature parameter, and then the multiple characteristic parameters respectively,with proper modification .The health indicator is used to fit the exponential model based on time series analysis to predict the health trend of the motorized spindle over time, and to estimate the reliable running time in the future. An example was presented to verify the rationality and feasibility of the proposed model. The results showed that the health indicator model is effective and could predict the reliable running time of motorized spindle.

Keyphrases: Reliable running time, health indicator, motorized spindle
