Abstract
This present thesis gives a brief compilation of research related to analysis of deformation, equivalent stress, fatigue life and natural frequency for lighter alloy and composite automobile Wheel rim. The design of wheel rim for car application is completed paying extraordinary enthusiasm for the optimization of the weight of the wheel. The lightweight material is considered because it enhances the wheels response on braking because of a decrease in rotational weight of vehicle. By the lessening in unsprung weight we can accomplish more precise steering and increase in fuel efficiency. By using the modeling software CATIAV5R18 the three dimensional Wheel rim model is designed and saved in IGES format. Later for analysis purpose, model is imported to most recently utilized software ANSYS Workbench 15. The fundamental thing is to direct a stress analysis of automobile rim by considering the loads act on it, The loading conditions are applied and bolt holes are constrained in six DOF, to analyze the static and fatigue analysis of four different materials, namely Aluminium alloy, Magnesium alloy, Titanium alloy and Carbon-Epoxy composite material and their relative performances have been observed individually. In addition to this rim is subjected to modal analysis, from this vibration analysis the natural frequencies and mode shapes of Wheel rim are obtained. In this dissertation work by observing the results obtained from Static, Fatigue and Modal analysis, Carbon-Epoxy Composite material can be suggest as the best material for wheel Rim. The finite element analysis shows that the weight of the wheel can be optimized to around 7%.
