A parameter-distributed model of turbogenerator shaft's torsional vibrations is put forwardbased on a four-terminal network model and the mechanical impedance method. The related software package is developed, which can be used to analyze the characteristic frequencies, vibration mode, stress distributions, and some performances else of turbogenerators'torsional vibrations. The model introduced in the paper isan accurate one, whose algorithm is simple and speedy.The developed software package is so practical that it canbe utilized to make some simulation studies on the realturbogenerators' shafts.
