Drgania osiowe fundamentów turbozespołów dużej mocy w świetle badań (Praca przeglądowa)

Up to date state of knowledge on the forced vibrations of turbogenerator foundations in the longitudinal direction is reviewed and discussed in the paper. Existing experiments both on the dynamically loaded foundations and on the model of the fram foundations are presented as well. It was found that the longitudinal amplitudes of the foundation – vibrations are large and increase with the power rating. Explanation of the phenomenon of longitudinal vibrations, as well as computation methods for the longitudinal dynamic load are outlined.
