有限元与优化在联合轴承求解中的运用

Using Finite Element and Optimal Methods to Solve the Joint Bearing Character

有限元素法以其独有的优点在流体润滑求解中得到广泛的运用 ,但在径向推力联合动静压浮环轴承 (以下简称联合轴承 )特性求解时 ,常面临迭代收敛速度相当缓慢的问题。本文给出了一种新的求解方法 ,即求解过程中综合运用有限单元法与优化方法 ,以加快收敛速度 。

Finite element method, with many merits, is widely used in solving lubrication problems However, when the method is used to solve the character of the radial thrust floating ring hybrid bearing (for short, joint bearing), the slow convergence speed of iteration is often encountered To solve the problem, this paper presents a new method of combining finite element method with optimal method
