FAILURE ANALYSIS AND OPTIMIZATION OF ROCKER ARM

Reduction of weight and improving the performance of components is on the top priorities in the manufacturing sector. In this view, this paper presents the study on the use of an advanced S-Glass Fiber material for the rocker arm. The theoretical and finite element analysis of rocker arm of diesel engine was performed. The percentage of variation in maximum deformation, maximum Von-Mises stress and maximum shear stress is observed to be 4.71%, 1.78% and 3.12%, which is acceptable. The obtained values of maximum deformation, maximum VonMises stress and maximum shear stress for the S-Glass Fiber were comparatively smaller than the corresponding values for the existing material of alloy steel for the rocker arm. Therefore, the proposed material of S-Glass Fiber provides more strength to the rocker arm and hence this material is suggested as a future material for the rocker arm of diesel engines.
