目前,燃气轮机转子很多是采用热套盘鼓式结构。过去计算这类转子振动特性,系将转子作为一整体来考虑,计算结果与实际相差较多。本文结合4000马力机车燃气轮机转子,对这问题进行了试验研究。 为此,对模型进行了七种方案的试验研究。同时,对实物转子用瞬态激振及正弦激振两种方法进行测试,并将模型转子与实物转子试验及计算结果进行了比较。所得结论如下: At present, many of the gas turbine rotor is the use of heat sleeve drum structure. The past calculation of such rotor vibration characteristics, the Department of the rotor as a whole to consider, the calculation results and the actual difference. In this paper, 4000 horsepower locomotive gas turbine rotor, the experimental study of this issue. To this end, the model has been tested in seven scenarios. In the meantime, two methods of transient excitation and sinusoidal excitation are used to test the real rotor, and the experimental and calculation results of the model rotor and the real rotor are compared. The conclusions are as follows:
