PRELIMINARY STUDY ON RELIABILITY DESIGN OF BLADE BY THE METHOD OF PROBABILITY[J]. Thermal power generation, 1992, (1): 12-18. DOI: 10.19666/j.rlfd.1992.01.003.
The design method adopted in the "Safety criteria for the Vibration Strength of Turbine Blade"
applicable now in China
is a classical method of safety coefficient. However
this method gives no consideration to the effects of random variables and their discreteness
so it can not quantatively describe the safety margins of turbine blade. This paper presents a theoretical study on the reliability design of turbine blade with the method of probability
which can quantitatively describe the reliability of turbine blade through the expolated formulas and the calculated reliability indices.
