Introduction
Recently there is a trend towards using it in the early stages of design.
A designer may use FEA just to validate the structural integrity of a design or she may use it for structural optimization along with the parametrized design techniques.This paper examines the requirements of a structural analysis agent and proposes an architecture to facilitate FEA in a concurrent design environment. The next section briefly describes how FEA is used in a typical industrial set up.Section 3 presents a survey of existing FE tools. Section 4 discusses some issues related to the development of an FEA agent. Section 5 proposes an architecture for the FEA agent that addresses the issues described in Section 4 and finally Section 6 presents the concluding remarks.
Steps in Finite Element Analysis
The process of FEA starts with identification of the region of interest and the formulation of the physical problem。[1]. The region of interest might be an assembly, a component or a portion of a component (or an assembly). The interaction of the rest of the assembly and the environmental conditions with the region of interest is captured in two ways. One way to represent this interaction is to idealize them as loads and displacement constraints on the region of interest. For example a spot weld fixing a component to a bigger structure will result in a constraining all the degrees of freedom at that point. The other commonly used method is to use spring and/or gap elements.
介绍
最近有一种将有限元分析用在设计早期的趋势。设计人员可以使用有限元分析软件来设计和验证结构的完整性或者优化参数设计技术。本文讨论了对结构分析媒介的要求，并且提供了一个在给定的设计环境下的有限单元分析的优化体系结构。下一节将简要介绍有限单元是怎样被用在典型工业的生产上的。第3节介绍了现有的有限元工具的调查。第4节讨论了一些涉及到有限元分析的发展问题。第4节发现的详细问题是有限元分析的起因，笔者在第5节对其提出了一个结构体系并在在第6节做出了总结。
有限元分析的发展
有限元是伴随确认重要部位和对物理学问题的构想进行的。[1] 重要的区域可能是一个配件、元件或者是元件的一部分。一个静止配件的配合和重要部件的环境条件是捕获的两种途径。----------------一种代表配合的方法是用理想化的负载和位移做为重要部位的系统规定参数。例如，把一个元件用焊接的方法固定在一个更大的部件上将导致这个点上所有的自由度受到约束。另一种常用的方法是使用弹簧或者间隙元素。---------------------
