Free Vibration Characteristics of Metallic Propeller Blade Replaced with Composite Material Using Finite Element Approach

Abstract:

Structural vibrations problems presents a major hazard and design limitation for a wide range of engineering problems. A comprehensive study of vibration phenomena includes determining the nature and extent of vibration response levels. This paper focuses in determining suitability of composite material in replacement of metallic material for assessing the dynamic characteristics of the blade. This study reviews the natural frequencies and associated mode shapes for a pre twisted composite propeller blade for marine applications. MAB and composite are used .composite with symmetric and balanced stacking sequence were analyzed. From the results it can be concluded that by further changing the layup sequence composite materials can be made much stiffer than MAB propeller.
