Modal Analysis Of Composite Propeller For Ships Application

Present work proposes a modal analysis to design a propeller with a metal and composite material to analyze its natural frequencies and mode shapes using ANSYS software. In order to evaluate the effectiveness of composite over metals, modal analysis is performed on both composite and metal propellers using ANSYS. Proposed method shows substantial improvements in composite propeller over the metal propeller.From the results of modal analysis composite propeller is safe against resonance phenomenon. In this paper effort is made to reduce frequency of the composite propeller so that advantage of weight reduction can be obtained. The comparison analysis of metallic and composite propeller has been made for the natural frequencies
