Abstract :
In this work, design and structural calculations of connecting rod of IC engine has been performed. From design point of view, connecting rod is most critical part as it the only part which converts reciprocating forces into rotating forces and thus creates unbalance in engine. From the functionality point of view, connecting rod must have the higher inertia at the lowest weight. The forces acting on connecting rod are: - Peak combustion pressure force, inertia force of reciprocating masses, Weight of Reciprocating parts and frictional forces due to cylinder wall thrust. It experiences complex loading of compression and tensile loadings under cyclic process, which repeats after each 360 phase. Therefore, the design calculations are analyzed for the axial compressive as well as axial tensile loads and considering the fatigue life of connecting rod. This work computes, the required strength and size in the critical areas of connecting rod. Connecting rod calculations, Fatigue, Endurance, Con rod, I C Engine.
