Fatigue and Fracture Analysis of Tacho-Way Drum Assembly using Finite Element Analysis

Structural design is very important for functionality and safety of the modules. Due to rotation and torsional loads, the components are subjected to changing stress amplitudes by which fatigue is the main mode of failure compared to the normal structural loads. In the present a drum conveyor system using tacho way guide ways is failure under the given loads. So aim is to find the possible cause of failure. The location of failure is near the bearing. For mounting of the bracket, the shaft has been cut with a small groove which is required for mounting of the bracket. So analysis needs to be done to find the effect fatigue and fracture effects on the configuration. So fatigue calculations are carried out based on Ansys, which shows nearing fatigue stress with minimum factor of safety in the problem. Further cracks are created to find the fatigue fracture life of the component. The result shows increased alternating stress with crack propagation showing that any possible crack will cause the failure of the drum shaft system.
