摘要
本文对巨型变压器钳夹式油箱结构进行了试验模态分析,并用模态试验得到的精确模态参数,检验和修正了油箱结构的动态分析数学模型.文中介绍了油箱结构模态试验方法和试验设备及有限元动态分析数学模型的修正,还对结果进行了分析和讨论.
The experimental modal analysis of the giant clamp type oil tank structure of a transformer was made by this paper. The mathematical model for dynamic analysis of the oil tank structure was corrected by the more precise modal parameters obtained by the modal experiments. The technique of modal experiment of the oil tank stracture, the apparatus used in the experiments and the correction of the finite element mathematical model of the dynamic analysis are introduced. The results obtained are analyzed and discussed.
