| Abstract: | Using the finite software ANSYS,the bearing support system＇s 3D finite element model is set up.The modes of the bearing support system are extracted through Lanczos model.The 1st to 6th inherent frequencies are calculated and corresponding vibration models are obtained.The rigidity frequency curve is gotten by harmonic response analysis.The influence of working frequency on bearing rigidity is analyzed.It provides a valuable theoretical basis for designing the bearing support system of dynamic balancing machine. |
