Abstract

The lateral vibration of the rotating slice disk blade was studied and analyze. Based on the structure and work condition of the rotating slice disk blade, using the finite element method and the Lagrange equation and the theory of the hydrodynamic lubrication, the dynamic equation of the rotating slice disk blade system was established that contain dynamical liquid film. it was analyzed by the equation that the liquid press film of rotating movement and lateral vibration form restrain lateral vibration of the rotating slice disk blade. The analysis results show that the liquid press film can be effective in reducing the amplitude of lateral vibration.
