本文以航空发动机中的离心叶轮为研究对象,以有限元原理及方法为基础,对离心叶轮主体的锻造过程进行仿真分析,得出锻件中残余应力的分布,并对锻件不同温度的淬火热处理过程进行仿真计算,研究残余应力的变化,为改善残余应力分布,避免加工变形与裂纹,提高加工质量与效率提供理论依据。 In this paper, the centrifugal impeller of aeroengine is taken as the research object. Based on the finite element method and the method, the forging process of the centrifugal impeller is simulated, the distribution of residual stress in the forging is obtained, and the quenching heat treatment process The simulation calculation is carried out to study the variation of residual stress, which provides a theoretical basis for improving the distribution of residual stress, avoiding the deformation and cracks during machining, and improving the processing quality and efficiency.
