Vibration Analysis of Compressor Blade with Arbitrary Blade Angles & Materials using Finite Element Method

The effective uses of a Compressor blade are limited at its maximum operational junction frequency. The study was conducted by using the Finite element method. The compressor blades are used with flow of with rotation such as power houses and industrial applications. The major study was done on compressor blade by using different materials with different blade angle profile of 50, 80, 120, 160. A natural frequency was analyzed and harmonic analysis is performed for validation. In our analysis, ANSYS was used and the model was developed on CREO 5.0. In order to verify the present ANSYS model, the Natural frequency with their modes by using four types of materials are compared with the available experimental results present in the literature. And the design of compressor blade with different angles of 50, 80, 120, 160. In this study, the simulations of different profile blade angles and four types of materials i.e. 304 structural steel, Aramid reinforced polymer composites, Carbon fiber reinforced plastic and ti-6al-4v, was analyzed for natural frequency and the configurations of blade design are proposed. The results show that increasing blade angle and material like carbon fibre reinforced plastic of compressor blade increases the frequency with increase in a number of modes simultaneously. The natural frequency of the compressor blade is compared by using four types of materials and is predicted that at 120, 160 blade angle profile a carbon fibre reinforced plastic gives better frequencies in different modes.
