Anti-seismic force calculation method for inclined camera shield support frame of nuclear fusion experimental device

Abstract

The application discloses a kind of anti-seismic stress calculation methods for the support frame of the inclined camera shield body of nuclear fusion experimental device, which comprises the following steps: 1, initialize simulation inclined camera shield body support frame working condition;2, carry out inclined camera shield body support frame static force working condition analysis;3, carry out inclined camera shield body support frame dynamic working condition analysis;Based on the initial working condition, modal analysis is carried out, the natural frequency and vibration mode of the structure are extracted, and the X direction and Y direction main vibration frequency of the structure are determined;Based on the modal analysis result, response spectrum analysis is carried out, seismic load is simulated, the dynamic response of the structure under seismic load is obtained, and 7-level earthquake acceleration spectrum is used for analysis;4, carry out inclined camera shield body support frame static force working condition and dynamic working condition comprehensive analysis;The present application effectively solves various problems in the design of the support frame of the inclined camera of the nuclear fusion experimental device in the prior art through accurate modeling, multi-working condition analysis and comprehensive evaluation.
