| 摘 要： | 本文采用单输入多输出（SIMO）的模态试验方法对圆筒法兰连接结构的下圆筒进行了自由状态下的模态试验，用频率多参考（Polyffequence）的模态拟合方法分析试验数据，获得了结构的模态参数，对其动态特性有了初步了解，试验结果可为圆筒法兰连接结构动力学建模提供模型修正数据。

| Abstract: | The article did modal experiments under freely condition to cylinder under flange joining structure using single input and plural output modal experiment method. It analyzed the test data using polyfrequence modal analysis method, and then got the modal parameters and dynamic characteristic. The results of the experiments can supply model amend data for dynamics modeling of cylinder under flange joining structure. |
