摘　　要：发动机旋转部件的强度分析是微型涡喷发动机设计过程中的重要组成部分,具有足够的结构强度是发动机正常稳定运行的保证。首先介绍了微型涡喷发动机离心压气机的国内外研究现状,并以KJ66涡喷发动机的离心压气机叶轮为例,分析了其结构组成及特点,并基于SolidWorks软件建立了离心压气机叶轮的三维模型;然后利用有限元软件ANSYS Workbench建立了有限元模型并进行了力学仿真研究。通过对离心压气机叶轮力学强度的模拟分析,为离心压气机叶轮结构进一步优化设计提供了一定的理论参考。The strength analysis of the rotating components of the engine is an important component in the design process of micro turbojet engines,and it is a guarantee for the normal and stable operation of the engine.This article first introduces the research status of centrifugal compressors for micro turbojet engines at home and abroad,and takes the centrifugal compressor impeller of KJ66 turbojet engine as an example to analyze its structural composition and characteristics.Based on SolidWorks software,a three-dimensional model of the centrifugal compressor impeller is established,and then a finite element model is established using the finite element software ANSYS Workbench for mechanical simulation research.By simulating and analyzing the mechanical strength of centrifugal compressor impeller,further theoretical references are provided for the optimization design of centrifugal compressor impeller structures.
