| Abstract: | Abstract. The mechanical model of looseness of anchor bolt on the bearing support was set up based on the project practice. Using the nonlinear oil- film model put forward by Adiletta, the dy- namic characteristics were investigated by numeri- cal Runge - Kutta method. At last, the experiment was made to investigate the pedestal looseness by model test rig and the fault signals were analyzed by the 3D waterfall spectra, trajectory and wavelet scalogram. |
| Keywords: | rotating machinery pedestal looseness faults numerical simulation wavelet scalogram experiment research |
