为了研究电力变压器绕组和铁芯的振动特性，利用模态分析方法分析了不同预紧力对绕组轴向振动的影响及铁芯压紧状态对铁芯振动的影响；采用ANSYS软件建立了绕组和铁芯的模态仿真系统，通过有限元分析法获得了绕组预紧力与轴向固有频率之间的关系及铁芯压紧状态与固有频率之间的关系。

In order to study winding and core vibration characteristics of power transformer, axial vibration of winding under different pre-compression and core vibration of different condition were analyzed. Mode simulation system of winding and core using ANSYS were established. By using finite element analysis method, the relationship of axial pre-compression and natural frequency of winding, the relationship of core condition and natural frequency were got.
