Performance Analysis of Gudgeon Pin of Various Cross Sections by FEM

Abstract

Gudgeon pin are one of most heavily stressed component present in engine Gudgeon pin is used in automobile engines to connect piston and connecting rod. and its failure can cause seizure of the engine. Thus they are carefully designed. This project deals with gudgeon pin of different inner profiles keeping the outer diameter constant which is equal to piston boss to provide a more strengthen gudgeon pin. Profiles investigated are hollow, uniform stepped, tapered, step taper. The models with mentioned inner profiles keeping outer profile straight are made using CATIA and then analyzed for using ANSYS for parameters maximum principal stress, equivalent (von-mises) stress, strain energy and total deflection. Considering all these parameters most suitable design of gudgeon pin is decided. On investigation of the different profile it was found that step taper profile gave the best results .Thus providing a stronger gudgeon pin leading to decrease in chances of failure.
