Vibration Control of Cantilever Beams Moving along the Axial Direction

In this paper a vibration control technique is proposed for a flexible body moving along the axial direction such as plates or wire rods in a mill, and the effect is verified by numerical simulation. The dynamic characteristics of the cantilever beam moving along the axial direction are examined by using Lagrange's equation of motion. It is shown that the vibration of the cantilever beam moving along the axial direction is caused by self-excited vibration, and that optimal damper-spring properties at the beam support point are obtained by examining the stability of a simple vibration model.
