The Stress Calculating and Analysis of the Second HP Turbine Disc of a Certain Type of Aeroengine

Abstract:

This paper takes the 2^nd HP turbine disc of an aeroengine as research object, construct its finite element model in software-Patran. According to the work environment of 2^nd HP turbine disc, the boundary conditions of stress field analysis and temperature field analysis are confirmed. Based on the finite element theory of thermal analysis and structure analysis, we use finite element software-Nastran to analyze centrifugal stress and thermal stress. Numerical calculation method was used to fit the data and finally we got the thermal elastic stress field. According to the computed results, the life assessment points of disc were confirmed. The static strength of 2^nd HP turbine disc was tested based on the EGD-3 criterion. All the work established the foundation for subsequent life analysis.
