Abstract: 

Because of the motion transferring role of connecting rod from piston to crankshaft, an accurate design of this part is of vital important. In this research the stress distribution in small-end during combustion stroke is obtained. 3-D finite element method (FEM) is employed to model the interaction of piston pin, connecting rod small-end and piston bosses in combustion stroke. Contact sections of the mentioned parts are modeled by employing enhanced contact elements. Non-linear analysis is performed to solve the governing equations. The results were compared with semi-empirical relations of other investigators in which good agreement would exist, besides it is shown that semi-empirical method cannot properly predict the critical stress distribution in combustion stroke.
