摘　　要：为验证非安全级DCS系统电源机柜在地震载荷作用下能否保证结构完整性,对电源机柜进行抗震分析;基于有限元分析软件ANSYS,通过谱分析方法对其进行地震分析,并依据RCC-M规范进行评定校核。通过抗震分析所得结论表明,电源机柜在地震载荷作用下,能保证结构的完整性,设计满足规范要求。In order to verify the integrity of the structure for the power cabinet of non-safety DCS under seismic load,the seismic analysis is carried out for the cabinet.and this paper use the finite element software ANSYS to create the model and seismic analysis is carried out by spectral analysis.Based on the finite element analysis software,the seismic analysis is carried out by spectral analysis method,and the evaluation and verification are carried out according to RCC-M specification.The results of seismic analysis shows that the power cabinet can ensure the structural integrity under seismic load,and the design of the cabinet meets the requirements of RCC-M.
