Stability Analysis of a Nonlinear Coupled Vibration Model ...

Mill chatter in tandem cold rolling mill is a major rejection to the quality and production of the strips. In most mill vibration models, either the roll mass is usually limited to vibrate in vertical direction and vertical-horizontal directions, or the multiple rolls system is simplified to a single mass system. However, the torsional chatter is also a typical type of mill chatter, and the ...

Analysis of Chatter in Tandem Cold Rolling Mills

backup rolls and torsion vibration of the drive system are the examples.1,2) The most likely instability caused in tan-dem cold rolling mills is due to vertical oscillations of rolls, and the typical frequency of chatter ranges from 150 to 250Hz. Also, it has been recognised to have close relation with friction conditions in roll bites.
