Abstract: This effort is anticipated with three-dimensional finite element model of a steam turbine blade having fir tree roots to obtain the blades vibration response with the variant in fixing state on blade root interfaces. Fir tree root of the object blade has three faces (Top, Middle, and Lower) of different contact areas at both side of blades, i.e., suction side and pressure side. In view of that, different contact configurations are considered and free vibration responses have been studied in all these cases of blade root fixity. At last, different variants of natural frequency and mode shape are obtained. © 2021, Springer Nature Singapore Pte Ltd.
