摘要
讨论一种用三维实体单元模型分析径流叶轮静态和固有频率的方法.采用MSC公司的Patran软件进行前后处理,Nastran软件进行分析计算,得到较为精确的分析结果.结果表明,分析模型可以精确直观地反映叶轮的静态和固有频率状况,为工程中实际叶轮的固有频率和强度分析提供参考.
A kind of three dimensional solid element model is provided to analyse static and dynamic characteristics of radial-flow impeller.The MSC compony′s Patran software is applied for pre-and post-processing and the Nastran software is used in computation with precise analytic results obtained.The results show that the analytic model can reflect static and dynamic characteristics of impeller directly and precisely,and give a worthful reference to strength and dynamic characteristics analysis of pratical impeller in engineering.
