Abstract
In this research, modal analysis of a second stage blade in a gas turbine is investigated and vibration modes of blade are found in various conditions. The numerical calculation by finite element method using NASTRAN-PATRAN software based on experimental test conditions is utilized and there is a good agreement between the experimental and FEM results. Finally by calculating excitation frequency in gas turbine work conditions and using a Campbell diagram, it is concluded that there is not any resonant problems in the blade and there is a good agreement between the experimental and FEM results as well.
