| Abstract: | In this paper,the properties of eigenvalues and eigenvectors of rotor systems are discussed.The derivation shows that eigenvalues are imaginary in non-damping systems,and eigenspaces are complete.The general solutions of vibration response and transfer functions are also derived in both damping and non-damping systems.These have important theoretical meaning in rotor dvnamics. |

| Keywords: | rotor dynamics modality orthogonality completeness transfer function vibration response. |
