有限元素法(又称有限单元法、有限元法)是一种求解工程技术问题的数值计算方法,能比较理想地解决一些具有复杂的几何结构和边界条件等较困难的问题。由于得到电子计算机的配合使用,更显出其优越性,近年来在流体力学方面的应用有所发展。下面介绍的“流体润滑问题的有限元素法”一文,就是这方面的一个例子。全文共分:前言;变分原理;剖分单元与插值;变分问题的离散化;刚度方程组数值解法与程序设计;有限元素法在静压轴承上的应用;结束语等七部分。本刊将分期连载。 Finite element method (also known as finite element method, finite element method) is a numerical method to solve engineering problems, which can solve some difficult problems such as complex geometry and boundary conditions. Due to the use of computer with the use, but also shows its superiority, in recent years, the application of fluid mechanics has developed. The following article, “Finite Element Method for Fluid Lubrication,” is an example of this. The full text is divided into four chapters: Preface; Variational principle; Split unit and interpolation; Discretization of variational problems; Numerical solution and programming of stiffness equations; Application of finite element method to hydrostatic bearing; This issue will be serialized.
