摘要
波箔轴承是一种弹性表面流体动压滑动轴承,在两维雷诺方程的基础上,本文给出了适用于波箔轴承计算的雷诺方程,结合使用差分法,可以求出它的压力分布曲线,并将其与刚性表面的流体动压滑动轴承作比较研究。
Bump foil bearing is one kind of hydrodynamic bearing with compliant surface. On the conception of elasto—hydrodynamic lubrication, the global Reynolds equation for foil Journal bearing is obtained in this paper. Using the finite—difference method, the curves of pressure distribution are described. It will be compared with curves of pressure distribution hydrodynamic bearings with rigid—surface.
