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.
介紹
最近有一種將有限元分析用在設計早期的趨勢。設計人員可以使用有限元分析軟件來設計和驗證結(jié)構的完整性或者優(yōu)化參數(shù)設計技術。本文討論了對結(jié)構分析媒介的要求，并且提供了一個在給定的設計環(huán)境下的有限單元分析的優(yōu)化體系結(jié)構。下一節(jié)將簡要介紹有限單元是怎樣被用在典型工業(yè)的生產(chǎn)上的。第3節(jié)介紹了現(xiàn)有的有限元工具的調(diào)查。第4節(jié)討論了一些涉及到有限元分析的發(fā)展問題。第4節(jié)發(fā)現(xiàn)的詳細問題是有限元分析的起因，筆者在第5節(jié)對其提出了一個結(jié)構體系并在在第6節(jié)做出了總結(jié)。
有限元分析的發(fā)展
有限元是伴隨確認重要部位和對物理學問題的構想進行的。[1] 重要的區(qū)域可能是一個配件、元件或者是元件的一部分。一個靜止配件的配合和重要部件的環(huán)境條件是捕獲的兩種途徑。----------------一種代表配合的方法是用理想化的負載和位移做為重要部位的系統(tǒng)規(guī)定參數(shù)。例如，把一個元件用焊接的方法固定在一個更大的部件上將導致這個點上所有的自由度受到約束。另一種常用的方法是使用彈簧或者間隙元素。---------------------
