摘　　要：采用条元法对连轧管芯棒速度及其摩擦对轧制过程的影响进行了理论研究，得到了芯棒速度与摩擦系数对轧制过程力能参数及变形参数间的影响规律。其结果与现有实验规律对比基本吻合。本方法研究轧管变形，具有计算费用低，输入数据简单的特点。AbstractWitb Finite Strip Method,authors have done theoretical study on the effect of mandrel moving speed and mandrel friction on continuous seamless tube rolling process and get their effect rule on force and deformation parameters in this rolling process.The obtained result is basically identical with experiment.It has the advantages of Iow computing cost and simple input data when using this method to study the tube plastic deformation.
