摘要
本文论述了识别电站锅炉墙结构固有频率与阻尼参数的方法．并对在上海石洞口发电厂２号锅炉上进行的测量及识别结果作了分析．
in this paper, two methods are discussed to identify the natual frequencies and damping of the structure of the furnace wall for large boilers of power plants. The results obtained by applying these methods to No. 2 boiler of Shanghai Shidongkou Power Plant are analyzed.
