Abstract：

The coupling vibration of the working roll of mill is an important factor to affect the quality of strip steel. According to the actual parameters of a mill F4, the mathematical model of the vertical and torsional coupling vibration of the rolling mill was established and solved, and the relationship between the vertical and torsional vibration of the rolling mill work roll was obtained. Meanwhile, the three-dimensional model of the rolling mill system was established. The key components were designed with flexibility by finite element analysis software ANSYS, and a rigid-flexible hybrid virtual prototype was established based on ADAMS eventually. Using ADAMS vibration analysis module, the dynamic responses of rolling mill work roll were simulated under different excitation conditions. The authenticity of the coupling vibration of the work roll and the reliability of the model were verified through the analysis of the measured signal. The analysis results show that there is a vertical and torsional coupling vibration in the working roll of mill, and the effect of the vertical vibration on the torsional vibration is obvious.
