摘要
提出了一种轧件自由宽展面鼓形率的定义。借助非线性有限元分析软件MSC.Superform研究了无孔型轧制过程中摩擦条件对轧件断面形状的影响,分析表明:轧件自由宽展面和角部的变形与摩擦条件有紧密的关系,尤其在大压下量的轧制状况下其影响更为显著。
A new parameter definition is given to describe the barreling shape.With the aid of non-linear FE software MSC.SuperForm, the effect of friction on cross-section shape of workpiece in grooveless roiling is analyzed. The conclusions are obtained that：there exist closely relations between friction and the deformation on the profile and the deformation of the workpiece＇s corner, especially when heavy draft is taken.
