本文根据Navier-Stokes方程,建立了一种新型的求解包括惯性项影响的有限宽滑动轴承流场的扰动法。本文提出的方法采用有限元方法作为求解工具,能考虑复杂的压力边界条件和不规则几何形状。本文中提出了一种新型的多步扰动法,使本方法能在一定雷诺数下考虑流体惯性影响。同时,本方法还能计及温度场的影响。 Based on the Navier-Stokes equations, a new perturbation method is proposed to solve the flow field of a finite wide-sliding bearing, including the influence of inertia term. The proposed method uses the finite element method as the solution tool and can consider complex pressure boundary conditions and irregular geometries. In this paper, a new multi-step perturbation method is proposed, which makes the method consider the influence of fluid inertia under a certain Reynolds number. At the same time, the method can also take into account the influence of the temperature field.
