摘要：

Here, to control vertical vibration and rocking effect of nuclear power plant under earthquake, it was necessary to explore adopting vertical isolation technology for CAP1400 nuclear power plant based on its horizontal isolation study. Combined with structural parameters of the inclined rotating type3-D isolation bearing and CAP1400 nuclear power plant, a theoretical model of vertical isolation for CAP1400 nuclear power plant was proposed to calculate relation curve among vertical vibration, rocking effect and stiffness of isolation bearing. Dynamic analysis was used to obtain the optimal setting number and spatial locations of isolation bearings. Then, the 3-D numerical model of CAP1400 nuclear power plant was established by using the large-scale structural finite element software ANSYS for verification. It was shown that the calculated vertical vibration acceleration, displacement and rocking effect of the nuclear power plant structure can satisfy the predetermined targets; the calculation method explored here can be applied in vertical isolation design of nuclear power plant structure as a reference. © 2021, Editorial Office of Journal of Vibration and Shock.
