摘　　要：基于有限元分析软件针对一台非晶合金干式变压器建模,并进行模态分析、振动位移的谐响应计算,提出设计改进方案。最后,以有限元分析所得位移结果为载荷,在声学软件Virtual Lab中应用边界元法对变压器表面声压进行了计算分析。Based on the finite element analysis software, an amorphors alloy dry-type transformer model is established. The model is analysed and calculated. The improvement solution is presented. Finally, using the analysis results as load, the transformer surface sound pressure is calculated in Vircual Lab software by boundary element method.
