Prediction and analysis of cold rolling mill vibration

A mill vibration monitoring system was developed to monitor the oscillating movements of the rolls in the tandem cold rolling mill A sketch of the rolling mill vibration data monitoring system and the specific locations of the sensors (locations A, B, C, and D) were shown in Fig 3Location A was the operation side of the bottom work roll (WR) bearing, location B Based on the analysis of the influence of roll vibration on the elastoplastic deformation state of a workpiece in a rolling process, a dynamic rolling force model with the hysteresis effect is established Taking the rolling parameters of a 1780 mm hot rolling mill as an example, we analyzed the hysteresis between the dynamic rolling force and the roll vibration Vibration Characteristics of Hot Rolling Mill Rolls Based According to the “Hill rolling force formula”, taking particular account of the influence from horizontal vibration of rolled piece in roll gap, a dynamic rolling force model is analyzed Considering the interaction between vibration of strip and roll, the dynamic vibration model of rolling mill is established On this basis, the time delayed feedback is introduced to control the Dynamic analysis and control of strip mill vibration under

Study on the Vertical Vibration Characteristics of Roll

Abstract： The corrugated roll mill often vibrates due to the influence of the roll shape curve in the rolling process of composite plateThe vertical vibration of the roll system of the corrugated roll mill will affect the stability of the rolling process,as well as the surface quality and bonding strength of the composite plate,even endanger the safety of the equipment in severe casesWhich The modal analysis method is employed to obtain the free vibration transmissibilities and force vibration responses under different road excitations A series of frequency characteristic analyses are presented to evaluate the isolation vibration performance between the mining vehicles with the proposed HIS and the conventional suspensionVibration Performance Analysis of a Mining Vehicle with Vibration Analysis Executive Summary Vibration is increasingly becoming a problem as machine speeds have increased and paper quality requirements have risen along with increased competition Balance grade G1 is requested and more time is spent on balancing the rolls in the machine However, by balancing, mills typically measure only thePublished May 10, 2011 Vibration Analysis Valmet

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 verticalhorizontal 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 Vibration Analysis A scientific approach to obtaining detailed information about the health of your rotating equipment Equipment failure as a result of excessive vibration may not only leave you with expensive repairs but can also greatly increase the safety risks to personnelVibration Analysis NECI The modal analysis method is employed to obtain the free vibration transmissibilities and force vibration responses under different road excitations A series of frequency characteristic analyses are presented to evaluate the isolation vibration performance between the mining vehicles with the proposed HIS and the conventional suspensionVibration Performance Analysis of a Mining Vehicle with
