| Damage form | The main damage forms of connecting rod are fatigue fracture and excessive deformation. Usually, the fatigue fracture occurs in three high stress areas on the connecting rod. The working conditions of the connecting rod require that the connecting rod has high strength and fatigue resistance; It is also required to have sufficient rigidity and toughness. |
| Structural composition of connecting rod | The connecting rod body is a long rod, which is also subject to large force in work. In order to prevent its bending deformation, the rod body must have sufficient stiffness. For this reason, the connecting rod body of vehicle engines mostly adopts I-shaped section, which can minimize the mass when the rigidity and strength are sufficient. H-shaped section is used for highly strengthened engines. Some engines use the small end of the connecting rod to spray oil to cool the piston, and a longitudinal through hole must be drilled in the rod body. In order to avoid stress concentration, the connecting part between the connecting rod body and the small end and the big end shall adopt large arc smooth transition. |
