The Design Of Steam Turbine Blade Vibration Characteristic Experimental Bench And The Study On Blade Vibration Characteristic

The integrated design is completed and the drive and the exciting device are reasonably chosen in the thesis. The vibration of the rotor and foundation stone is analyzed and they are completely designed. The development of testing method is summarized and the sensor is used in non-contact testing the vibration of the blade .The equation of freeness vibration blade is deduced by 3-D incompatible block and the author programmed the program of blade vibration in the thesis. The thesis studied the effect of the different crack on crack blade vibration characteristics.Fan Xiaoxu(Thermal power engineering) Directed by prof. Ding Changfu, Han Zhonghe...
