ANSYS FE-SAFE概述
ANSYS FE-SAFE由用戶界面、材料數據庫管理系統、疲勞分析程式和信號處理程式組成。
ANSYS FE-SAFE讀取有限元分析計算出的單位載荷或實際工作載荷下的彈性應力，然後根
據實際載荷工況和交變載荷形式將結果比例迭加以產生工作應力時間歷程；也可換算成特
定類型載荷作用下的彈塑性應力。
材料數據庫管理系統
ANSYS FE-SAFE提供了一個全面的材料疲勞特性數據庫和數據庫管理系統，含有上百種常用
的鋼、鋁合金材料的疲勞數據，用戶也可以根據需要擴充和修改該數據庫。
用戶可以查訊數據庫，如列出所有的鋁合金，也可以輸入新材料。
如果有主數據庫和用戶本地數據庫，這兩個數據庫都可以訪問；系統管理員可以將主數據
庫設定為只讀，以防止用戶對主數據庫的數據進行修改。
利用內置的Netscape link可以訪問試驗報告及背景數據，在啟動疲勞分析時程式可自動訪
問材料數據庫，讀入材料數據；用戶數據可通過用戶界面直接輸入。程式還可繪製材料數據
的多種類型的曲線。
在數據庫中含有Seeger材料近似算法，允許利用材料的抗拉強度（UTS）和彈性模量生成近似
的材料疲勞數據，生成的數據可以指定一個數據集名並存入數據庫。
Many companies use advanced finite element analysis to calculate
design stresses, but the fatigue analysis is often still done by
manually picking stress points for spread-sheet analysis. This is time
consuming and unreliable because it?s easy to miss failure locations.
Component validation by fatigue testing a prototype design in the test
lab is time-consuming. If the prototype fails prematurely, a costly,
open-ended cycle of design-test-redesign is required. Project
time-scales slip and delivery is late.
In the automotive industry some 40% of the total development cost is
spent making prototype parts. In the medical industry an unexpected
failure can mean the loss of several months lead-time over
competitors.
fe-safe?is a highly effective tool for fatigue analysis of Finite
Element models.
With fe-safe?as an integrated part of your design process, you have
the ability to optimise designs and test programs, reduce prototype
test times product recalls and warranty costs - all with increased
confidence that your product designs pass their test schedules as
?right first time?
fe-safe?
calculates fatigue lives at every point on a model, producing
contour plots to reveal fatigue lives and crack sites. Critical points
need not be missed.
determines how much the stresses must be changed in order to
achieve a target design life showing clearly where the component is
under strength, or where material and weight can be saved
estimates warranty claim curves based on probabilities of failure
calculates which parts of the service duty are most damaging and
which could be omitted from a fatigue test
identifies non-critical loads at significant points on a model. In
prototype testing this could mean tests using fewer loads and
therefore fewer actuators
