碩士 === 華梵大學 === 機電工程學系博碩專班 === 96 === The aim of this paper is to study the static stree and the dynamic vibration characteristics for the transformer using the Finite Element Method .The transformers in power plants are very important for transmitting electrical power The stregth of the transformer trank must be enough to avoid the occurring of yielding and fracture .The stresses distribution of the transformers tanks were analyzed for elastic deformation and plastic-strain hardening respectively.This study can offer the useful information to judge whether the design of the shells correspond to the requirements of the standards.In the mean while the vibration due to natural-frequency resonance is very important and should be considered simultaneously.
