Abstract: The pendulation of payload was caused by the motion of ship which induced by wave. The motion equation was obtained by means of the relative position of the payload, The kinematics model of ship-mounted crane payload system was established using Lagrange equation, the dynamic was carried out in Matlab/Simulink simulation environment, the influence of rope length, excitation frequency and lifting speed on payload pendulation was analyzed in a comparative manner. The simulation results showed that the payload swing angle increased first and then decreased with the increasing of the rope length; meanwhile, the swing angle increased with the excitation frequency approaching the natural frequency of the system; finally, the swing angle tended to increase with the increasing of the lifting speed, however, the swing angle decreased with the increasing of the lowering speed. Experiment was carried out, and the accuracy of the simulation results was verified.

Key words: ship-mounted crane, payload system, pendulation, kinematics model, Matlab/Simulink software
