摘要
介绍域外法在处理弹流润滑问题时的应用。和边界元法相比,域外法不需要对边界单元作繁琐的奇异积分处理,因而编程简捷、计算精确。作为算例,用域外法联立求解雷诺方程和弹性变形方程,计算了大型可倾瓦推力轴承的油膜压力、弹性变形和相应的静特性参数。
The out-domain method is introduced and used to solve two dimensional lubrication problems and three dimentional elastic deformation problems. Compared to the boundary element method, the present method not only holds the advantage of freedom reduction, but also has the superiority over the boundary element method because the singularity in the integrals along the boundary can be now avoided. As an example, the oil film pressure, the elastic deformation and the static performance of a tilting-pad thrust bearing in heavy-loading condition are calculated by using the out-domain method.
