套装叶轮应力和过盈变形分析
摘要
本文采用ANSYS通用结构分析程序对套装叶轮轮孔处的应力和变形位移进行了计算分析
通过分析三种不同结构的叶轮轮孔型线
指出传统的叶轮结构存在着很大的应力集中现象
推荐了改型优化的叶轮轮孔结构。分析计算结果表明
有限元法是进行叶轮应力和变形分析以及对叶轮进行改型设计的有效手段。
Abstract
This paper presents a calculation of stress and displacement on the blade wheel of shrunk-on disk. Three different disk structures were analysed by using ANSYS program. It was found out that the traditional design of wheel structure had a serious stress concentration. A modified design with optimized bore curve is recommended. The result shows that the Finite Element Analysis is an effective method for stress and displacement analysis
which should be used to replace the traditional Two-Time Calculation method.
