动压推力轴承的边界元分析

本文利用Green第二公式,将Reynolds方程转化为沿边界的积分方程,并将非线性项作为自由项的一部分处理,采用常单元离散边界Γ,用迭代技术求出油膜压力分布,与有限差分法和有限元法比较,边界元法的结果更接近解析解.

Boundary Element Analysis of Hydrodynamic Thrust Bearings

In this paper Reynold's equations are changed to integral equations along boundary by Green's second formula,and nonlinear treated as a part of free items. By means of the constant element discrete boundary, iterative methods are used to solve oil film pressure distribution. Comparing with the finite difference method and the finite element method,the result by the boundary element method is more approachable to analytical solution.
