| Abstract:Aimed at the fracture of a certain diesel’s connecting rod, research was carried out on the fatigue machining of small-end lubricating holes and residual stress controlling technology of surface shot-blast treatment. Based on the research results, the traditional machining technic was improved. The field test and small batch trial production verified that the residual stress of the connecting rod produced with new machining technic was controlled within the reasonable range. |
