چکیده:

The main propose of this article is the investigation of influences of crack parameters on vibration characteristics of turbine blades. This paper consists of two main part. In first part, modal analysis experiments were done on some cracked turbine blades and it’s proccess has been described. In second part, Finite Element Method (FEM) was used to analysis the effects of variation of depth and location of crack on blade’s vibrational characteristics. Finally, by comparing the results, it was shown that FEM results were in good agreement with experiments.
