Abstract
Abstract: The Aim of this paper is to study failures in radiator fan blades due to Resonance and optimization in design, which will withstand the failure conditions. The Modal Analysis is carried out in ANSYS and it is validated through Experimental Techniques. The correlation between modal analysis and experimental analysis is determined. Suitable material which withstands the resonance is determined and validated in ANSYS and FFT Analyzer. In absence of design data, the reverse engineering process is considered as a major tool for modeling. Using the data the solid model of the radiator blade is created in CAD. We have used modal analysis to calculate the natural frequencies and mode shapes of a Radiator fan. The natural frequencies and mode shapes are critical components in the design of any structure. Experimental Analysis is accomplished using FFT Analyzer with DEWESOFT software. The final results of CAE model and Experimental tested model are correlated. Keywords: Natural Frequency, Mode Shapes, FFT, FEA.
