摘　　要：建立准确描述体系动力特性的有限元模型是应用反应谱理论进行抗震计算的关键,以公司SCB10-800/6.3变压器为例,建立了干式变压器本体及外壳结构的有限元模型,计算了体系的模态并与实验结果进行了比较,分析了建立干式变压器抗震模型的关键问题。The key problem of the seismic calculation based on the response spectra theory is to set up the finite el- ement model which can describe the dynamic behavior of the system accurately. Taking the SCB10 - E - 800/6.3 transformer of Pearl electric Co. Ltd. as and example, the finite element model of main part and crust of the dry type transtormer was set up. The modes were calculated and compared to the experimental results. The key problems of building dry type transformer aseismatic model were analyzed.
