By test and analysis, includes changes of relative bearing elevation and vibration, it is found that shafting eleva- tion is unreasonable.This is one of rimary factors that brings vibration of turbo-generator.In this a er, the measuring rinci le of relative elevation and the analytical results of elevation and vibration are discussed.The adjustment roject of shafting elevation is resented.Unstable vibration is eliminated thoroughly in this turbo- generator unit.
