【Abstract】 In order to decrease the roof whiplash effect of ship lifting under the earthquake,the Pan-Boolean algebra logic control rule is established and a logic control algorithm is designed in accordance with the control experience of ship lifting structural vibration.The Pan-Boolean algebra logic control algorithm is used to control the existing ship lifting structure model by the Matlab/simulink simulation.The results show that the control method is not only simple,flexible,convenient and effective,but also suitable for the typical ship lifting structure with obvious damping effect and it meets the engineering requirements of earthquake resistant control of ship lifting.更多还原
