Description

Two degree of freedom system represented by an equivalent mass-spring-damper describing chatter in sheet rolling is investigated. The dynamic behavior of the roll and excitation test indicated that chatter phenomenon is encountered in tandem cold mill wherein the roll stack vibrate in both vertical and horizontal directions. This paper assumes a friction model of the arc contact in roll bite which depends on the horizontal vibration of roll, and explains the vertical vibration in chatter is coupled with the horizontal one and therefore, both vibrations have influence on the dynamic behavior of the rolling force. The results of these analysis show the unstable area in the coefficient of friction producing a self-excited vibration and chatter phenomenon is caused by both excessive lubrication and inadequate one in the roll bites.
