Research on Fatigue Life and Failure Mode of Riveted Joints During Transportation of Monolithic Castings
The fatigue properties of riveted joints during the whole machine loading section of castings were studied.The fatigue properties of the two riveted joints were tested by manual riveting and robot automatic riveting,and the fatigue life of the test pieces at different load levels was obtained by statistical method,and the fracture analysis was carried out by electron microscope to deduce the fatigue failure mechanism,and the fatigue life and failure forms of the two joints were compared and analyzed,which was the application and promotion of the automatic assembly technology of the whole machined casting the theoretical foundation has been laid.
