Fatigue Analysis of Motor Cycle Alloy Wheel

Abstract

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.
