EXPERIMENTAL MODAL ANALYSIS OF A DISCMILL FIBERIZER DISC (VIBRATION, PLATES, RESONANCES)

Date Issued:

Summary:
Modal analysis testing techniques were used to determine the modal parameters and mode shapes for flexural vibration of a Fiberizer Discmill disc to help define a safe operating speed range. The modal parameters and mode shapes were determined for the first six diametral modes, the first concentric mode, and the first rigid body shaft mode. The disc consisted of a circular aluminum plate with eight equally and symmetrically spaced radial cutters on one face of the disc and eight equally spaced peripheral cutters located on the rim of the disc midway between the angular locations of the radial cutters. All cutters were of tool steel. The safe area of operation is determined to be between 3000 rpm and 3600 rpm. The experimental setup and procedure Is described in detail with particular emphasis on validation of assumptions required for the analytical approaches used in calculating the modal data.
