The relationship between bearing vibration and foundation vibration in 600 MW units was studied from the view of the linear velocity’s root-mean-square (RMS) value and linear displacement of control point’s vibration, based on the summary of the related standards and the experimental data, and the evaluation standards for the turbo generator units was also compared. Moreover, this paper investigated the composition of vibration energy at bearing chock and interference point, in order to provide reference for the further research of the relationship between units and foundations.
