| Summary: | Geometric model was created by 3D software and imported into the finite element software ANSYS for finite element modal analysis. The frequencies and modes were compared with unconstrained state and different boundary conditions. The bogie frame of high-speed trains in traveling status was tested and the modal parameters were identified. The weak position of the frame was found based on modal strain energy analysis. The curves of the displacement of nodes at the weak position with the frequency were obtained, providing a scientific basis for the further analysis of the dynamic response and the improvement of the structure. |
