摘　　要：对世界首台两缸两排汽2伊660MW超临界空冷机组基础1:10模型进行了动力特性研究,通过测试得到了基础的各阶振型和频率,对基础的强迫振动响应进行了预测,将预测结果和TGFP杆系计算结果进行对比,并结合原型结构的实测结果,验证了模型试验和计算结果的准确性,为设计人员研究超临界空冷机组提供了大量有价值的参考。Research on the dynamic performance of 2 × 660MW supercritical air cooling units foundation model （1：10） is carried out in Phase II Project of a power plant. According to the test, the vibration mode and frequency of foundation are obtained. And then the forced vibration response is predicted. The prediction and the result of TGFP are compared. Combined with the test result of prototype, the accuracy of model test and the analysis result are validated. And then it provides many important references for designers to research on supercritical air cooling units.
