Abstract
In this study, the dynamic model of horizontal vibration of two kinds of shaft misalignment state is proposed for the dynamic analysis and diagnosis of shaft misalignment state. In order to obtained the solution of the vibration equations and clarify the feature of the vibration signal measured in shaft misalignment states, we show the calculation method of vibration forces caused by misalignments. The results of computer simulations and experiments using rotating machine are also shown to verify the efficiency of the dynamic analysis method proposed in this paper. Finally, the method for distinguishing shaft misalignment state from imbalance state is discussed.
