Wheels in the motor cycle play major role to carry the load. Generally spokes are subjected to fatigue loads. So it is necessary to study the response of the wheel under fatigue loads. In the present work different shapes of the wheel spokes are modeled and analyzed their response for fatigue loads by using finite element simulation software ANSYS workbench. The shape of the spokes used for the alloy wheels are curved, inclined, Y shape, Triangle shape, V Shape and H shape with constant volume. The material parametric study is also performed on the different cases of the spokes. The materials used are Structural steel, Aluminum alloy, Carbon steel and magnesium Alloy. The results show that the carbon steel shown better results when compared to remaining materials in view of life, damage and factor of safety. V curved with pad shape possess high life, high factor of safety and low damage factor compared with the remaining models.

Alloy wheels in the motor cycle play major role to carry the load over the spoke wheels. The shape and orientation of the spokes are responsible for withstand the loads which are acting on the alloy wheel rim and hub bearing surface. These alloy wheel spokes are subjected to different types of loads i.e., radial loads, impact load, bending load, torsion load and maximum deflection load. So it is necessary to study the response of the wheel under these types of loads before the product going into the market. In the present article 4 models of motor cycle alloy wheel are modeled based on the dimensions in the reference article. The material chosen for the analysis of the alloy wheel is aluminum alloy which is homogenous in nature having isotropic properties. The magnitude of the five different loading conditions and boundary conditions are taken from the Automotive Industry Standards (AIS). The four models of alloy wheels are analyzed under radial, impact, bending, torsion and maximum deflection loads cases by using by using ANSYS workbench. The results show that all four models are having enough fatigue life, strength and stiffness against the different loading conditions.
