Analysis of a CNG Driven Three Wheeler Drive Shaft

Abstract

CNG driven three wheeler vehicles is seen to carrying passenger around Bangladesh and vary favorable as public or private hired vehicle. Its drive shaft is a vital component for transmitting power from engine to wheel rotates at around 4000-5000 rpm. Most shafts undergo varying range of loads including bending, torsion and axial simultaneously. Therefore, the shaft fails frequently. But the problem of its replacement is difficult. It is imported from abroad; usually from the origin country of a specific model which makes its interchangeability exorbitant to the owner but also time consuming due to unavailability throughout the country. Substituting high cost unoriginal drive shaft by locally made shaft is an important criterion for lowering the maintenance cost. In this work an attempt has been made to estimate the deflection, stresses under subjected loads using FEA in ANSYS. The static structural analysis gives deflection and stresses. Modal analysis shows the nature of frequency and the maximum permissible rotating speed.
