Seismic Response Analysis of Container Crane

摘要

Earthquakes pose a threat to large-scale container cranes.Previous earthquakes damaged many container cranes,which had a significant impact on business interruption losses of the port.In this paper,a container crane's seismic response is analyzed in ANSYS.First,a finite element model of a container crane is developed.Then,based on the equations of structural dynamics,the four most important modes of the container crane are extracted.Finally,a time history analysis is conducted to obtain the displacements of some critical nodes on the crane model under the excitation of an earthquake wave.The result of this paper provides a reference for the seismic design of container cranes.
