| Abstract: | This paper discusses that concentrate parametric shafting torsional vibration model for a large sized turbogenerator unit built by finite element method is identificated and modificated by incomplete modes using tests. In the paper modification equations of model parametric matrix are built by use of minmum manifold theory, and computation for 200 MW generator set mode in China is done, effect of the model modification method is verified. |
