摘　　要：为进一步分析轧辊弹性变形对板形的影响,介绍了轧辊弹性变形影响函数解析方法,采用C语言编写了轧辊弹性变形解析软件,对四辊CVC冷轧机轧辊的弹性变形进行了模拟计算,结果表明,工作辊与支撑辊的挠曲均呈不对称的"V"形分布,辊间压扁量与辊间压力均呈"S"形分布。整个调控范围内支撑辊挠曲和工作辊与轧件间的压扁量变化较小,工作辊挠曲和辊间压扁量的变化较大,且集中在边部。The influence function method of roller elastic deformation was introduced so as to analyze its effects on profile shape.The roller elastic deformation of 4-high CVC cold mill was calculated by analytic program using C language.The results show that the deflection of work roller and backup roller are in asymmetric＂v＂style,the inter-roller flattening and pressure are in＂s＂style.In the whole controlled area the change of backup roller deflection and the flattening between work roller and strip is small,the change of work roller deflection and inter-roller flattening is large,especially at the edge.
