Fatigue Failure Analysis

Especially in the small and middle scale agricultural machinery industry, insufficient awareness and use of new technology, and new design features can cause problems such as breakdowns and failures during field operations. Failure of machinery devices is one of the major problems in engineering. Tractor is one of the multifunctional machines that are used for different agricultural operations. Because the tractors work on difficult conditions than other machines, components of that should have high safety of factor. Its main components must be resistant to tolerate additional stress and loads as some of its component may face additional stress. This additional stresses may cause the parts to failure or face permanent deformation. Trolley axle is a supporting shaft or member on which a wheel revolves. The axle is fixed to its surroundings with the wheels rotating around the axle. A bearing or bushing sits inside the hub with which a wheel or a set of wheels revolves around the axle. A premature fatigue failure analysis that occurred prior to the expected load cycles in the tractor trolley rear axle is done in the present work.
