This paper obtains the distribution range of steam turbine blade´s static response by non-probabilistic interval analysis method. To improve the strength reliability of blade, the uncertainty of the material properties, Geometry parameters, load, and speed of turbine blade must be considered. Based on the uncertain factors of influencing the static characteristics of the steam turbine blade, expressed the distribution range of blade´s uncertain parameters by the interval model, established the mathematical model of a static response of the turbine blade, expressed the deformation and stress of blade as interval variables, the distribution range of response function can be obtained. By comparison with the paper´s result and stochastic finite element method´s one, that shows that the method in the paper simple and effective. This method provides a new line of analysis for the reliability based on the stream turbine blade´s uncertainty.
