【Abstract】 The sensitivities of natural fiequencies of torional vibration to structure parameters of shaft series are analyzed by the theory of sensitivity. A design method for the torsional vibration characteristics of shaft series of a simulant tuibine-generator is developed. The procedure has been made and used in the optimimum design and dynamics analysis of torsional vibration of shaft seiies of the simulant turbine-generator, which can simulate the torsional vibration characteristics of the shaft series of 300MW tuibinegenerato. And the designed result is satisfactory.更多还原
