Numerical and experimental assessment on the vibration characteristics of hollow shaft system

Abstract

Vibration is the behaviour of the body changes under action of oscillating forces Vibration occurs in the body by elastic constraints and is classified as natural or free damped and forced Basically when a high frequency obtained in the component it will create crack automatically and sometimes it will break This research is mainly focused on the vibration reduction in hollow shaft material with different cut out section Hollow shaft is an important mechanical component used in various applications of power transmission The material stability of the hollow shaft has been affected due to the dynamic characteristics of an application The stability is confirmed based on the material behaviour based on the requirements So the selection of material has been altered to improve the stability In this research work the stable material is declared by variable analysis of vibration characteristics on the hollow shaft i e experimental and numerical The anisotropic hollow shaft is prepared by the combination of carbon and epoxy CE The analysis work is carried on the hollow shaft made up of mild steel and anisotropic with variable cut outs of corresponding newlinespecimen shape The hollow shaft of 363 mm length 100 mm ID and 150 mm OD has been considered in this study Two kinds of cut out shapes circular and square and two boundary conditions Clamped Clamped CC and Clamped free CF have been considered throughout the study as described in the nomenclature section newline newline
