摘　　要：根据离心压气机结构设计方案,利用CAE前处理程序建立了可以准确描述离心压气机叶盘结构特征和力学特征的有限元模型,通过离心压气机叶盘结构的载荷环境和约束条件,计算得到了线弹性范围内的静强度分析结果,并给出了相应的分析和评价。According to the structure design scheme of centrifugal compressor,a finite element model that is able to accurately describe the structure and mechanic characteristics of the centrifugal compressor impeller has been established by CAE pretreatment procedure in this article.Based on the load environment and constraint conditions of the centrifugal compressor impeller structure,the static strength analysis result in the range of linear elasticity has been calculated,and the analysis and evaluation details have been given.
