摘要
ANSYS有限元分析软件在钢架结构力学分析中正在被广泛地使用,而且由于其分析速度快、精度高而成为当今有限元分析的主流软件。本文以一种典型的屋架钢结构为例,说明了ANSYS在随机振动分析中的应用,对有限元力学模型的建立提出了自己的见解,并对后处理结果进行了简要分析,最后给出了随机疲劳计算过程。
ANSYS Finite Element Analysis(FEA) software is being applied extensively to the mechanics analysis of steel-truss structure . It has become the international representative software due to its fast operation speed and high-grade operation . Following the example of a kind of typical steel-truss structure , the article has explained the application of ANSYS Finite Element Analysis software in random vibration analysis . For the establishment of Finite Element Analysis mechanics model , the article has put forward the authors points of view , and has briefly analyzed the result of after-treatment . At last , the article has given the process of random-fatigue calculation
