摘要
运用有限元分析方法，对具有隔震基础的高耸瓷质电气设备进行了动态特性分析和地震反应研究。提出了适合于该类设备地震反应分析的理论计算模型与算法。通过工程实例计算，讨论了该设备的抗震与隔震等问题，为该设备的国产化定型设计提供了一定的理论依据和指导性设计准则。
By FEM, the dynamic properties and seismic response are studied for the high and porcelain electrical equipment from abroad. We present the computational model and algorithm which are suited for this kind of equipment. With computing the real engineering structure, we discuss the antiseismic and other problems of this porcelain eguipment. At last, some computing foundations and guide theorems to the domestic design of this equipment are proposed.
