| Abstract: | Pertaining to the structural properties and actual working conditions, a 3D mechanical model is established for port container cranes using the finite element analysis method. In order to obtain the frequency distortions that are resulted from external excitations, the modal analysis, resonant response analysis and instantaneous analysis are conducted based on each imperil frequency order. Therefore, this approach provides a dynamical method for container crane design. |
