摘　　要：基于普通中板四辊轧机,运用影响函数法分析了轧件宽度、支撑辊半径、工作辊半径、支撑辊凸度和工作辊凸度对轧机横向刚度的影响。仿真结果表明1)随着支撑辊半径的增大,轧机横向刚度线性增加;2)随着工作辊半径增大,轧辊横向刚度接近线性增大;3)随着支撑辊凸度增大,轧机横向刚度非线性增加;4)随着工作辊凸度增大,轧机横向刚度非线性增加,但是工作辊凸度的变化对轧机横向刚度影响较小;5)随着轧件宽度的变化,轧机横向刚度呈现高次曲线。6)在轧件宽度、支撑辊半径、凸度以及工作辊半径、凸度一定时,轧机横向刚度不变。根据大量计算数据进行回归,建立了轧机横向刚度模型。Based on the four bigb mill,the influence of backup roll radius,work roll radius,backup roll crown ,work roll crown and plate width on horizontal rigidity of four high mill has been analyzed.Resuh show tha：1）horizontal rigidity is increasing linearly when backup roll radius is increasing;2）horizontal rigidity is increasing almost linearly when work roll radius is increasing;3）horizontal rigidity is increasing nonlinearly when backup roll crown is increasing ;4）horizontal rigidity is increasing nonlinearly when work roll crown is increasing;5）horizontal rigidity prest is high order curve when plate width changes;6）horizontal rigidity is constant when backup roll radius, work roll radius, backup roll crown, work roll crown and plate width are fixed. The Horizontal rigidity calculation model is developed by lots of data.
