Abstract

The purpose of this work is to suggest a new non-contact diagnostic method applicable to rotating shafts. The presence and the location of any damage in rotating shafts are assessed by means of longitudinal elastic waves propagating along the shafts. These waves are measured by magnetostrictive sensors that make use of the coupling between strains and magnetic induction in ferromagnetic shafts. These sensors have been successfully applied in pipes and others, but it appears that the present application of them to rotating shafts is made here for the first time. Several issues appearing in the magnetostrictive sensor application to rotating shafts are carefully investigated. The usefulness of the present method is verified by several experimental results
