摘要:

应用有限元分析软件ANSYS建立了EAST装置外杜瓦结构的三维有限元计算模型。在模态分析的基础上,根据《核电厂抗震设计规范》要求设计的地震响应谱作为输入条件,对EAST装置外杜瓦结构进行了地震响应分析计算。计算结果表明,地震动作用下EAST装置外杜瓦的位移和应力响应比较小。依据评判标准,EAST 装置外杜瓦结构设计在地震动作用下能满足抗震设计强度要求,能保证装置的抗震安全。

Abstract:

A 3-D finite element model for EAST tokamak cryostat is established by using ANSYS. On the basis of the modal analysis, the seismic response of the EAST tokamak cryostat structure is calculated according to an input of the design seismic response spectrum referring to code for seismic design of nuclear power plants. Calculation results show that EAST cryostat displacement and stress response is small under the action of earthquake. According to the standards, EAST tokamak cryostat structure under the action of design seismic can meet the requirements of anti-seismic design intensity, and ensure the anti-seismic safety of equipment.

Key words: EAST tokamak, Cryostat, Structure anti-seismic, Seismic spectrum design, Seismic response spectrum analysis
