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.

In this paper, the experimental modal analysis of the giant transformer clamp-type fuel tank structure is carried out and the mathematical model of the dynamic analysis of the fuel tank structure is verified and corrected with the accurate modal parameters obtained from the modal test.The paper introduces the modal test methods and tests Equipment and finite element dynamic analysis of the mathematical model of the amendment, but also the results were analyzed and discussed.
