To study the hysteretic model of disc spring isolation (DSI) bearings

the mechanical property and deformation performance of DSI bearings were investigated

and the Origin-oriented (OO) hysteretic model of DSI bearings was proposed. The mechanical performance of a typical DSI bearing under reversed loadings was studied

and the OO hysteretic curves of the DSI bearing were investigated

whose results were used to verify the OO hysteretic model of the DSI bearings. The results indicate that the OO hysteretic model of the DSI bearings had the characteristic of asymmetry

and the friction forces had significant influence on the OO hysteretic force characteristic. The tested load-displacement hysteretic curves of the DSI bearing had the characteristic of asymmetry under reversed loadings.The loading frequency had little influence on the mechanical property of the DSI bearings

while the loading amplitude and vertical load had great influence on that of the DSI bearings. As the dynamic load amplitude increased

fullness of the load-displacement hysteresis curves of Model E gradually decreased

and the asymmetry of the curves gradually increased.As the preloading displacement increased

the load-displacement hysteresis curves of Model E tended to be full

indicating that its energy dissipation capacity gradually increased.Moreover

the OO hysteretic model can simulate the mechanical performance of the DSI bearings effectively

and the errors between the simulated results and the experimental results were within 8%.
