摘要:: 本文采用3-D有限单元法,对发动机叶片进行了应力分析计算。在形成单元刚度矩阵时,采用了不协调位移模式和协调位移模式。本文还给出了叶片在危险截面处的应力变化面线以及应力集中因子,为叶片的寿命估计、可靠性分析提供了依据。

Abstract:: This article adopts a 3-D limited unit method, and the engine blades are calculated and calculated on stress. When forming a unit rigidity matrix, an uncoordinated displacement mode and coordinated displacement mode were adopted. This article also gives a basis for the stress changes and stress concentration factor at the dangerous cross section, which provides a basis for the life expectancy and reliability analysis of the leaves.
