Abstract
In order to research the dynamic characteristics of drive roll, finite element model of the drive roll was set up by ANSYS/Workbench. The drive roll’s natural frequency and vibration mode concerned in reality were acquired based on modal analysis, deformation trend and size of each mode shape were analysed, then deformation of the weak positions about each mode was cleared, and some measures about improving its dynamic characteristics were proposed, all of these offered a support to strengthen drive roll’s damping property.
