| Abstract: | This paper introduces the fatigue/endurance calculation procedure of aeroengine's turbine components.The actual cyclic load spectrum of an aeroengine is worked out based on the analysis of FPR data,and the high pressure turbine rotate-exhaust temperature correlation time matrix is obtained by statistical analysis.Futher more,this paper indicates the differences between therotical load spectrum and actual load spectrum.By analysing the distribution of the temperature field and stress field,the life assessmen... |
