摘　　要：介绍了MS9001E燃气轮机轴承支座动刚度现场测试试验,描述了试验原理及数据处理方法。分析了9E燃机轴承支座结构动刚度实测数据结果。给出了实测处理后的频率与动刚度关系。这些数据为研究此类燃气轮机转子支承结构的等效刚度提供参考。Dynamic stiffness field test on bearing supports of an MS9001E Gas Turbine is introduced, including test principle and data processing method. The field test data is disposed and relation curves between dynamic stiffness and frequency are produced. These da- ta could provide reference for equivalent stiffness study of similar gas turbine supporting structure.
