Internal combustion engines have progressed since they undertook a crucial role to convert chemical energy of fuel mechanical with the reciprocat-ing motion piston. Structural elements performed under heavy con-ditions their facing dynamic stresses especially on connecting rod compression and tensile stresses. To overcome these stresses, manufacturing methods design studied by engineers for dif...

To optimize a connecting rod satisfying fatigue life, metamodel-based design optimization is proposed. To approximately predict both volume and fatigue life of connecting rod, kriging metamodel is constructed based on maximin eigenvalue sampling. Fatigue analysis is accomplished for the calculation of fatigue life. The results of metamodel-based design optimization are compared with those of cl...

The connecting rod (CR) is the main moving parts and an important component of engine. If the reliability is not strong enough, fatigue failure of the CR would occur, thereby leading to component fracture and engine failure. So much so that CR fracture. It will lead to engine fault as well as serious outcome. In this paper, stress distribution and fatigue life of CR in light vehicle engine were...
