Modularized rotor data generating method used in calculation of shaft system of power generator

The invention provides a modularized rotor data generating method used in calculation of a shaft system of a power generator. A generality calculating program is programmed by using MathCAD software. The method comprises the steps of: firstly, calculating a cross sectional moment of inertia of a power generator body; secondly, modularizing a power generator, calculating parameters such as moment of inertia and weight of each segmentation module; and finally outputting required various shaft system data. According to the method provided by the invention, the defects of the prior art are overcome, the calculation of shaft system data is modularized, and the shaft system data can be conveniently and rapidly arranged and output, thus the error rate of data processing is reduced, a data format suitable for shaft system calculation can be rapidly generated, and a complex manual input process is avoided.
