An Investigation of Comparative Study in Connecting Rod by using Finite Element Analysis

Most of the automobile parts are connected with the help of connecting rod. More vibration occurs on the engines. This project deals with reducing the vibration and calculates the natural frequency of the engines. The top end of the connecting rod is connected with the bottom of the piston and the other end is connected to the bottom of the crankshaft. The crankshaft rotates some amount of energy transfers through connecting rod. The connecting rod and crankshaft are transfer few rotation motion to the piston. The piston is moving transverse direction, so it is necessary to find out natural frequency. The result of this research deals with the natural frequency of two different materials, namely Cast iron and stainless steel. The design of connecting rod is done with the help of CATIA V5R17 and modal analysis is done with the help of Ansys software. The result of model analysis i.e. natural frequency of two different materials is compared and results tell that the natural frequency of cast iron is less in comparison to stainless steel. Where the deformation in cast iron takes place in the10th layer of the node, whereas the deformation takes place in stainless steel in 8th layer itself. By this comparison, it is justified that natural frequency, i.e. deformation in cast iron is less in comparison with stainless steel.
