Theoretical design and experimental verification of a 1/50 scale model of a quayside container crane

Abstract

An effective way to study the dynamic performances and seismic behaviours of large-scale engineering structures is using a scale model. This article aims to develop a geometric-scaled model of the 1/50 for a quayside container crane such that the dynamic characteristics of the prototype can be accurately predicted from the relevant features of this scale model. To this end, a detailed design process for the main components of a 1/50 scale model of the quayside container crane was first presented according to the similitude law. Then, a hammering modal test and the Ling dynamic system shaking table test were successively carried out to obtain the dynamic characteristics of this 1/50 scale model. Furthermore, the experimental results were compared with the computed results of the prototype obtained from numerical simulation and they showed a fairly good agreement. From the comparison results, it can be seen that the model design is instructive enough to provide some valuable information and practical use for professionals and researchers involved in the design of large-scale port facilities.
