本文耦合了流体动力润滑理论,经典轧制理论及弹性接触变形理论,并计入了润滑油的压粘效应和轧制材料的硬化效应等因素,运用有限元法和边界元法等计算方法,分别得到了刚性轧辊下的理论解、弹性轧辊下的Boussinesq解及边界元解,预示了轧带工作区的压力、剪应力以及膜厚的分布规律,确定了最小油膜厚度,并对计算结果与实验结果进行了比较。
In this paper, the theory of hydrodynamic lubrication, the theory of classical rolling and the theory of elastic contact deformation are coupled. The factors such as the pressure-tack effect of lubricating oil and the hardening effect of rolling material are also included. By using the methods of finite element method and boundary element method, The theoretical solutions under rigid roll, the Boussinesq solution under elastic roll and the solution of boundary element are obtained respectively. The pressure, shear stress and film thickness distribution in the working zone are forecasted, and the minimum film thickness is determined. The experimental results were compared.
