摘要
文章从多物理场耦合关系出发,建立变压器电磁—振动—噪声数学模型,借助COMSOL有限元分析软件对其进行仿真,将仿真结果与实验数据进行对比分析,从而验证数学模型的合理性和有效性。最后,将以有源消声原理为基础的降噪技术应用到变压器的降噪中去。
Based on the coupling relationship of multi-physics field, this paper established a mathematical model of transformer： electromagnetism vibration noise,using COMSOL finite element analysis software to simulate,the result of which is compared with experimental data, so as to verify the rationality and validity of the mathematical model.Finally, noise reduction technology, based on active noise control, will be applied to the noise control of transformer.
