Design and Static Analysis of Connecting Rod of a Petrol Engine Using FEA

The connecting rod is one of the functional elements of an IC engine. It transmits the gas force from the reciprocating part to the rotating part of an engine. The design of connecting rod majorly influences the performance of an IC engine. In the present work, the design and finite element analysis are carried out for connecting rod of a 124 cc Honda Shine bike. The modeling of the connecting rod was carried out using SOLIDWORKS® 2017–18 software. The performance of the connecting rod was analyzed by finite element analysis using SOLIDWORKS® software. The static stress analysis was performed under cyclic tensile and compressive load of 4702.64 N. The I-type connecting rod has the maximum stress of 235 MPa with factor of safety of 2–4.2. The newly designed connecting rod has decreased stress and increased factor of safety compared to existing I-type connecting rod.
