Performance Evaluation of Pulley Arm Design

Here in this study CAD method has been explored to design and analysis of pulley arm and belt, which considered being the main parts of a rod cutting machine. The cutting speed of a present system of pulleys and belt is very low in actual working conditions. The ultimate aim of the project is to increase the cutting speed Finite Element Analysis was done for investigation of stresses experienced by the pulley. Finite Element Method (FEM) is used to determine the BM shared by the arms for its different angular positions. The distribution of bending stress in the arms is also obtained. Finally, the design modifications have been suggested the parameters, By using this parameters the new design is developed which is able to give the cutting speed which is required for the actual working conditions. The results showed that stress experience by the pulley is less than the young�s modulus of the material. This ultimately enhances the life of the pulley and belt. It is also observed that the total deformation is very less and not crossing the bounding box limits. Hence part is safe.
