MODEL ANALYSIS OF STEAM TURBINE BLADE

The objective of this research is to study the influence of various blade geometric parameters on its modal properties. In this line, first of all the effect of pre - twist angle has been investigated on the modal properties of the blade. Secondly, modal analysis results of a blade have also been found out by modelling the blade including all the geometric properties. It is important to design steam turbine blades in such a way that the natural frequencies of the blades remain away f rom the harmonics of the excitations forces. This can be ensured by carrying out the modal analysis of the steam turbine blades.
