Finite element analysis modeling of full scale 5-ton electric overhead travelling crane and the crane supporting structure

摘要

The current codes of practice for the design of structures do not explicitly account for the flexibilities and interactions of the Electric Overhead Travelling Crane (EOHTC) and the crane supporting structure. This leads to analyzing member forces in the EOHTC and the crane supporting structure separately for ease of computation. Thus, the interaction of the various components of the EOHTC and crane supporting structure are ignored, which results in an incorrect assessment of the member forces. This paper describes howa computationally efficient Finite ElementAnalysis (FEA) model of a full scale 5-ton experimental model was developed to predict the global responses of EOHTC and crane supporting structure when subjected to various loading conditions. The FEA model was developed through many simplifications taking cognisance of the limitations of the simplifications. Finally, a comparison between the experimental and FEA end buffer impact forces are provided and discussed.
