Analysis and modelling of the rotor dynamics of a composite hollow shaft using finite element techniques

Abstract

Composite materials have been used more and more over the years, mostly in the aerospace and auto industries. This is because there are so many ways to get the proper properties for different uses. Composite shafts are growing in popularity as a practical solution to the problems present in metallic shafts, and one of the most promising applications is in rotor dynamics [1,2].Composite materials can be used to replace traditional shaft materials since they have high specific strength and modulus without compromising the component's dependability. Composite materials are made up of two materials that have distinct physical and chemical characteristics. It is lighter and stronger and can provide design flexibility and provide resistance to corrosion as well as wear. Compared to conventional materials, composite
