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.

Vertical crosshead forces are sometimes contained by the foundation, but in some applications the stiffness under the crosshead guide is too low, and high vibrations result. In many cases, a rigid body analysis of these forces shows that the vector sum of the forces from all of the crossheads is zero. Such an analysis can be misleading.
