【Abstract】 The paper puts forward a concept of sensitive eigenvector of torsional-vibration of a turbine-gener- ator shaft and a method of its analysis. Taking the existing generating unit as example, the paper calcu- lates and analyese the sensitivity of such eigenvector to the shaft system, the inertia of each section of the shaft and the rigidity of connection. The most sensitive parts of each model of different order are also determined.更多还原
