Abstract
As a working platform supporting the normal operation of the generator set, the turbo-generator foundation, its dynamic characteristics are very important to the safe operation of the whole set. In this paper, a finite element model was established according to the measured size of the turbine generator foundation, and the finite element software ANSYS was used to perform a static analysis on the foundation of the turbo-generator, and the deformation and stress cloud diagrams were obtained. The results shown that the local stress concentration phenomenon occurred in the foundation, which leaded to the high tensile stress at this stress position of the foundation. Then, the modal analysis of the foundation was performed to obtain the natural vibration characteristics of the foundation. Then the time-history analysis and calculation of the foundation structure under earthquake action were carried out. The results shown that the foundation of the turbo-generator met the seismic requirements, and the earthquake action had little influence.
