Analysis of Turbine Blade under the Effect of Damping with Different Materials

摘要

Critical operating conditions of turbine blades for its effective life is the present need of the industry. In this aspect a typical analysis is performed on a turbine blade in this research work. In the first stage an analysis is performed taking into account of thermal loading and with combination of mechanical loads for the evaluation of displacements and stresses to locate the critical area in the model. Later in the second stage under the effect of damping factor 0.001 and natural frequencies of blade is investigated using commercial Ansys soft ware with different materials. A solid 185 brick element is chosen for the analysis and the simulated results were analyzed for comparison with materials like Nickel base Alloy and Ti-6 Al-4V
