摘要

轧制界面的粗糙形貌可导致界面行为的根本变化，极大地影响着轧机辊系的动力学响应行为。考虑轧制界面粗糙形貌的影响，建立了轧机辊系系统的非线性垂直振动动力学模型；计算了具有不同粗糙形貌轧制界面的轧机辊系系统非线性刚度特性和固有频率特性，并与采用Duffing振子描述界面刚度的传统轧机模型进行了对比；采用多尺度法求解了考虑界面粗糙形貌影响的轧机系统主共振幅频特性方程，并推导了系统受迫振动响应的跳跃频率和跳跃幅值表达式，分析了轧制界面粗糙形貌、激励载荷、非线性刚度率和阻尼对轧机辊系系统动力学响应特性的影响，为抑制轧机振动提供有效的理论参考。

Abstract

The surface topography of the rolling interface can change the interface dynamics,and influences the dynamic response of a rolling mill system.Considering the roughness of the rolling interface,the nonlinear dynamic model of the rolling mill system was established.The nonlinear stiffness and natural frequency characteristics of the rolling system with different rough surface topography were calculated and compared with the traditional rolling mill model using Duffing oscillator to describe the interface stiffness.The main resonance amplitude-frequency characteristics of the rolling mill system were solved by using the method of multiple scales,and the expression of the jump frequency and the corresponding amplitude of the forced vibration response were derived.The influence of the rolling surface roughness,excitation load,nonlinear stiffness ratio and damping on the dynamic response characteristics of the rolling mill was analyzed.The results provide theoretical reference for suppressing rolling mill vibration.
