Control of lateral vibration of slice-disk cutter rotation

The lateral vibration of the high-speed rotation slice-disk is controlled using the hydrodynamic film and the control of the disk was studied by the finite element method and the experimental measurement. The slice-disk was meshed by elements of the fan-shaped grid. A dynamic equation of the rotation disk was established by the Lagrange equation and the theory of the hydrodynamic lubrication. The static and dynamic characteristics of the disk system were analyzed by the equation. A special experiment set was developed and used to measure the lateral vibration displacement of the disk. The measured data were compared with the theoretical analysis. The comparison shows that the dynamic equation established is correct. And present work gives a technique method of decreasing the lateral vibration of and increasing the stability.
