Abstract :

The connecting rod is a key element in the four–stroke engine. It connects reciprocating piston to rotating crankshaft, transmitting the thrust of the piston to the crankshaft. Connecting rods engine for automobiles are generally manufactured by two different processes: the steel forging and forging of the metal powder. Each forging process, steel or metal powder is characterized by its advantages and disadvantages. Approximately, 80% of the connecting rods in Europe are steel forged as opposed to 43% in North America. In order to recapture the US market, the steel industry has focused on development of production technology and new steels as C70. The connecting rod is generally manufactured for infinite life period and the model criterion has limited power. It is solicited by loads of compression, axial tension, multi–directional bending force of inertia and torque.In this work: First, we make a kinematics, dynamics and thermodynamics study, to determine the compressive and traction loads on the connecting rod. Secondly, we apply the loads on the two types of connecting rods Thirdly, using Mathematica, Cast3M and finite element method, we investigate and compare fatigue strength of C70 steel forged connecting rods with that of the powder forged connecting rods.
