摘要
用大型通用软件MSC/MARC对叶片 /盘组件进行了三维接触有限元分析 ,给出了某些工况下其应力分布规律 ,并对接触分析的计算结果与常规方法所得计算结果进行了比较分析。结果表明接触有限元分析更符合实际情况 ,计算结果更可靠。
Three dimension contact finite element analysis of blade and disc assembly is made by means of software MARC,and the distributions of stresses are given under some load conditions.Furthermore,the calculated results are compared with those of taking no account of contact.The results show that they are more reliable and more accordant to engineering practice.
