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 contamer 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.
