2) Here is another problem. The separator of Raw mill is adjacent to the raw mill vertical structure. When the raw mill runs, the vibration from the Raw mill is being transmitted to Separator (motor and its gearbox), and the whole unit of motor and gearbox moves (like if they are on the hanging foundation).

Kinematics and tool-workpiece separation analysis of

Feb 01, 2018 A unique feature of vibration assisted machining is tool-workpiece separation (TWS), which brings many benefits in machining process. Generic kinematic equations of vibration assisted milling are firstly formulated, then three types of TWS mechanism are proposed and the requirements to realize each type of TWS are discussed through kinematic analysis and simulation.

Analysis of Vertical-Horizontal Coupling Vibration

Nonlinear dynamic rolling forces in the vertical and horizontal directions are, respectively, established, considering the impact of vertical and horizontal directions vibration of rolls. Then a vertical-horizontal coupling nonlinear vibration dynamic model of rolling mill rolls is proposed, based on the interactions between this dynamic rolling force and mill structure.

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
