摘　　要：采用影响函数方法开发了四辊轧机轧辊弹性变形解析模块 ,完善了辊间压扁和工作辊压扁影响函数计算模型 ,克服了轧辊压扁影响函数计算过程浮点数被零除的缺陷 ,提出了平滑指数和收敛指标取值的处理方法 ,有效地解决了四辊轧机辊系弹性变形计算精度及收敛问题。该模块适应于普通四辊轧机、PC轧机和CVC轧机轧辊弹性变形计算 。The calculation module of rolls elasticity deformation in 4-h mill was developed by influence function method The calculation model of influence function of rolls flattening was improved The disadvantage of division by zero was overcome in floating point calculation The treating methods of smoothed exponential and convergence index were introduced The problem of calculation precision and convergence was solved The module was applicable for calculating rolls elasticity deformation in conventional 4-h mill,PC mill and CVC mill It would be a useful tool in shape and flat control in hot strip rolling
