Abstract

This paper presents an approach to optimizing the location of vibration sensors on a spindle, based on the concept of Effective Independence (EfI).  The study is aimed at investigating the effect of sensor placement on spindle vibration measurement, and its significance on the effectiveness of identifying multiple defects within a spindle support bearing, for spindle health monitoring.  A large set of initial candidate locations were ranked based on the strength of the respective sensor signal output, as well as on the individual contribution to the linear independence of the measurement data.  Iteratively, sensor locations having the lowest EfI value are removed from the candidate set one after another, until a pre-determined number of locations is reached.  The effectiveness of such  a location selection approach was experimentally evaluated on a spindle test bed.  The result indicates that the EfI-selected sensor locations are effective indetecting the localized bearing defects.
