The dynamic behaviour of a mechanical component is characterized by the modal parameters such as natural frequencies and mode shapes associated with each natural frequency. Many researchers spent considerable amount of time and effort in obtaining the modal parameters of the twisted cantilever beam. In this paper, comparison of modal analysis is made for twisted cantilever beam and the steam turbine blade for different angle of twists. So, parametric studies have been carried out using ANSYS software to evaluate natural frequencies and mode shapes for different angle of twists i.e. 15, 30, 45, and 60 degrees of steam turbine blade and twisted cantilever beam. From this analysis, the effects of the angle of twist on the natural frequencies of the blade and beam were studied. This analysis is believed to know the exact dynamic behavior of the turbine blades compared with twisted cantilever beam.
