Abstract

Abstract: The bending vibration equations are established on the multi-supports rotor model system. For calculating mode of free vibration, the dichotomy and LU law are adopted, while the Newmark law and quincunx difference are applied to dynamical response calculations. In a model of a 300 MW turbine generator, the results of calculation are basically identical with the on-the-spot measurements, as accounted for validity of the equations and the laws.

Key words: Bending vibration, Difference method, Mode analyses, Multi-supports rotor, Response calculation
