Finite Element Analysis of Two Disk Rotor System used in Automobile Turbochargers
Main Article Content
Abstract
Turbochargers are the devices which increase efficiency of the driving engines. For power boosters in engine such type of device is using in present scenario. Due to the complex design of turbocharger, its analysis is very difficult. A lot of literature is present about turbochargers but the complete analysis by using finite element method is rarely found in past. In the present work, a two overhung-disk rotor mounted on a shaft is modelled as turbochargers for sake of simplicity. Moreover, finite element analysis method is used for the complete analysis of the system. The Campbell diagram and eigenvectors are plotted for different modes for vibration analysis of the proposed system. Along with this, amplitude and phase response are also plotted with respect to rotor spin speed.
