Design and Analyze the Optimum Operating Point between Magnetic FluxDensity and Vibration Noise of Transformer Cores

Base on the magnetization and magnetostriction measurement, this paper proposed a generalized 3D finite element numerical model, which can be used to analyze electromagnetic vibration of laminated cores including electromagnetism and magnetostriction effects. And then the acoustic field around the transformer was analyzed and tested, the results showed the model and analysis method were feasible. The work is helpful to estimate vibration noise level and then optimized design, choose suitable silicon steel and size in the design stage, which can reduce product development cycle and test cost.
