Abstract:The influences of power spinning process parameters on the mechanical properties of spinning parts were analyzed with an SXD100/3-CNC numerical control power spinning machine. The unidirectional tensile tests were carried out. Based on the experimental data, a ternary quadratic regression equation was established by orthogonal experiment. The Ramberg-Osgood constitutive model of tin-bronze connecting rod bushing was obtained. Referred to the constitutive relation of macroscopic incremental, the incremental elastoplastic constitutive relation of spinning parts was deduced based on the Mises yield criterion and kinematic hardening model. The results can be applied to the elastoplastic analysis in finite element numerical simulation.
Key words: power spinning; connecting rod bushing; constitutive model; technical parameter; mechanical properties
