非线性粘弹性本构方程及其在弹流润滑中的应用

Nonlinear viscoelastic constitutive equations and their application in elastohydrodynamic lubrication

文中将线性多组元粘弹性模型在两种不同坐标系中推广从而得到两个非线性粘弹性本构方程，并用这两种本构关系对弹流中摩擦拖曳力进行计算，取得了新的结果。

The rheology in lubrication region is studied in this paper with. Two nonlinear viscoelastic constitutive equations are derived by generalizing the linear viscoelastic model in moving and co-rotational coordinate systems respectively. Line contact elastohydrodynamic lubrication traction is investigated theoretically by these two constitutive equations. And some significant results are obtained.
