Dynamic Analysis of Motorcycle Engine Rod Bending and Fracture Failure

Abstract:

Taking Motorcycle Engine as the research object, force analysis of the single cylinder engine connecting rod bending and fracture by engine linkage dynamic model. By calculating the connecting rod compression, combustion chamber total pressure, reciprocating movement of the inertia force and from the rod bend parameters to compare the models currently on the market four types in the working state suffered total stress and strength margin safety factor, found that the safety factor of four models in general partial link is small, especially 152QMI engine connecting rod end connecting rod in the hole near easier to bend and break. This study provide a scientific basis for the engine connecting rod design, the quality of correction and failure analysis.
