Vibration Analysis of Isotropic and Orthotropic Turbine Blade Using ANSYS

摘要

In this paper focuses on vibration characteristics of turbine blade made up of isotropic and orthotropic (composite) material. The whole research is been carried out in two phases i.e. modeling and modal analysis. Firstly in modeling phase the blade is modeled by using CREO in such as way that parametric analysis can be done and in second phase i.e. analysis the blade is subjected to a cantilever mode and the natural frequency is been computed.Moreover, a comparative analysis between the blade material natural frequencies has been done also with the presence of cutout of different shapes such as circle and rectangle having same volume and mode shapes is generated and reveals the effect of cutout shapes factor in over all stability of turbine blade.
