【Abstract】 This paper deals with the strength analysis for turbine disk of aeroengine. A finite element analysis program of thermoelastoplastic creep is formulated,which imitates a cyclic loading in flight. Considering the influence of factors of creep, change of material’s properties, and process of temperature elevation,the stress analysis of the disk-body is accomplished under various working conditions. Moreover, the residual stress resulting from a cyclic loading is calculated. Some useful conclusions have been drawn for engineering design.更多还原
