| Abstract: | The data processing of load spectrum for cress-flow turbine runner is made out by new rain-flow counting model and three parameter Weibull distribution mathematical model in this paper,P-S-N curve of the turbine runner is established by means of the three parameter power function model and fatigue strength of the turbine runner is calculated by means of the reliability design. On this base, safely used head and respective reliability of various runner in the given life are presented. |
