| Abstract: | A new and simple method is developed to determine the stress in runner'sblades of a francis turbine, based on the power output data collected in situ.With the power output data statistically analyzed, the stress distribution atany point in a blade will be obtained as a loading spectrum used for stess-design and also an important information for the fatigue strength calculationof a runner. |
