Virtual Prototype and Modal Analysis of Stator System of Large Turbo-Generator

Abstract:

The stator core is an important part of large turbo-generator .The its natural frequency must be to avoid the operating frequency and the double frequency. In this paper, stator core structure of 1000MW generator is considered as the research object. In the Pro / E software, its virtual manufacturing model is built for design and manufacture of stator core; In ANSYS software, a parametric finite element model is established for virtual experimental modal analysis; The virtual prototype model in the different constraints (free, and different constraints) and different core parameters (such as the core inner and outer diameter, length) is used to analyze and solve its natural frequencies and mode shape changes. For design, manufacturing and on-line monitoring and fault diagnosis of a variety of large-capacity turbine generator, the research approach and results provide an important basis.
