Abstract
The microstructure and mechanical properties of the domestic fracture split connecting rod made of non quenched and tempered steel were analyzed. Fatigue test of the rod was carried out. The fatigue performance was studied by SAFL data processing method. The fatigue fracture was observed. Finally, the safety coefficient of application for connecting rod was assessed. The results show that the composition and mechanical properties of fracture split connecting rod could meet the relative idex demands of Germany C70S6 steel. The fatigue performance and safety of the fracture split connecting rod made of non quenched and tempered steel can satisfy application demands, its safety margin was enough.
