Abstract

Heavy transporter plane is the carrier for segmented hull in modern shipbuilding. Its positioning accuracy directly affects the installation accuracy of hull, therefore it is necessary for the heavy transporter plane to improve the accuracy of leveling control by hydraulic automation. The leveling strategy of coplanar type is proposed for adjusting the heavy transporter plane and avoiding the virtual leg with four-point positioning. Furthermore, AMESim and Matlab/Simulink are used to establish the simulation model of rising-leveling system for improving the hydraulic suspension of the heavy transporter plane. Considering the nonlinear and time-varying properties in hydraulic suspension system, the control strategy with dual-mode fuzzy controller is employed to converge the systemic leveling error promptly and improve the positioning accuracy and dynamic performances of the hydraulic suspension. The simulation results show that control strategy with dual-mode fuzzy controller performs a higher positioning accuracy and anti-load interference with a shorter adjusting time. The control strategy can meet the practical requirement with a precision 2.0mm for leveling positioning when the segmented ship is docked.
