In this paper, a rigid body model and a two-mass model shaking table seismic isolation test are performed for a ball-supported rolling isolation system with a reset capability. The effects of mass ratio, natural frequency and stiffness on the isolation performance are discussed. Correctness. The results show that compared with the basic fixed structure, the ball-supported rolling isolation system has a significant effect of isolation.
