本文对主梁的颤振导数识别，采用与主梁颤振分析试验相同的节段模型和测量装置，以自由振动法进行试验。
This paper makes use of free vibration method, using the same model and measuring device to identify the flutter derivatives of the girder.
实验仪器测试平台是准确测量的重要物质基础，它受到的振动可归结为单自由度的振动问题。
Experiment instrument testing bench is important matter foundation for accurate measurement. Vibration comes from a single variance.
