本文提出了基于有限差分法的浅油腔动静压轴承动特性分析的偏导数法,并利用该法分析了两种在国产磨床中常用的浅油腔动静压轴承的动特性. In this paper, the partial derivative method based on the finite difference method is proposed to analyze the dynamic characteristics of shallow oil-chamber hydrodynamic bearings, and the dynamic characteristics of two shallow hydrodynamic bearings which are commonly used in domestic grinders are analyzed.
