Analytical and Experiment Study of the Vibration of Operating GHM Horomill SHEN Zu-wu,HUANG Zhi-chu,CHAI Yan-hong (School of Mechanical and Electronic Engineering,WUT,Wuhan 430070,China)On the basis of analysis of the configuration and work principle of the Holirontel-Roller-Mill(the horomill),the vibration model of the roller is formed,and the vibration analysis of the roller is included. A blue print is advanced,which is used to restrain swing and vibration of the roller formed by machine and oil cylinder together. Its feasibility is the measurement and analysis of field test.horomill; roller; vibration analysis
