Shaft alignment using strain gages: case studies
TL;DR: In this paper, measurement and modeling programs were undertaken to assess the installed shaft alignment condition on marine vessels, including the CCGS Earl Grey and the HMCS Huron, where catastrophic damages had previously occurred to shaftline components, which were suspected to be a result of shaft mis-alignment.
