| Abstract: | Taking JiangYin 500kV guyed transmission tower as the case study, on-site dynamic vibration measurement is analysed, which was excited by the random environment micro-quiver. Also, the process of the experiment and the method of mode identification are discussed in details. In the end, dynamic parameters of the guyed tower are presented, including frequencies, flutter states, and damping ratios. |
