Modeling And Simulation For The Vertical Vibration System Of Cold Rolling Mill

The vertical vibration of rolling mill was studied here. The cause, damage and major factors were illustrated preliminarily. Based on the theory of flexible multi-body dynamics, the 4th-stand flexible-body model of the 1676mm 4-stand tandem cold rolling mills was built integrated the softwares of SolidWorks, ANSYS, ADAMS. The factors of vertical vibration were analysed by the simulation which supplied the theory basis for the vibration restraint. The functional superiority of different field softwares was integrated, and the collaborative simulation was realized through data-conversion interface. The stand and work roller in rigid model were flexibilitied which proposed a valid method for accurate simulation of heavy-duty equipment.
