Modeling and Simulation of a Container Gantry Crane Cabin's Operation with Simulink

This paper deals with the simulation of a ship-containers' gantry crane cabin behavior, during an operation of load releasing. The goal consists of obtaining a reliable model of the cabin, with the aim of reducing the non-desired cabin vibrations. We present the Simulink-based model and the simulation results when the load is released by the crane in the containers' ship. We conclude that the mass center position of the cabin affects dramatically to the vibrations of the crane. A set of graphs are presented involving displacements and rotations of the cabin to illustrate the effect of the mass center position's bias.
