@@@@The finite element model of a 4‐hi cold rolling mill is developed with Workbench software .Based on structure modes and dynamic response analysis theory ,the natural frequency of vertical vibration and response characteristics were obtained by using mode analysis and harmonic response analysis .And the axial distribution of vertical displacement response of work roll when backup roll’s bearing seat on operating side was excited was explored .
