Design improvement of table fan blade in term of its vibration characteristic using finite element method

Abstract

The main purpose of this paper is to improve vibration characteristic, which is natural frequency, of fan blade to get a good natural frequency. An existing table fan model TF1610 of three speeds with 16 inches blades was used for the study. To complete this study, finite element method has been used to perform the simulation and the analysis of the table fan blade. Components of the table fan are drawn using CATIA software. By using finite element software, the drawn table fan design was run for the analysis and the simulation to get the natural frequencies of the table fan blade and compared with the natural frequencies of the motor. The results show that, for Polycarbonate material, shape 4 is considered as the best shape. Shape 2 is considered as the best shape for Polyethylene Terephthalate and Polypropylene material.
