FEM and Experimental Modal Analysis of a Large-Scale Quayside Container Crane

In this paper, FEM modal analysis and experimental modal analysis methods were used to investigate the modal performance of the metal structure of a quayside container crane. The analysis results indicated that the relative error of both methods was reasonable small, and that most inherent vibrations of this crane were in the horizontal plane. The influence of vibrations caused by mass eccentricity of container and wind loads should not be ignored. The present results can provide a reference for solving similar problems in the future.
