Dynamic Simulation of Tension Control of Ocean Winch System under Different Impact Directions
The tension control of the ocean winch system is mainly used to balance the impact of the complex and ever-changing ocean environment on tension.When the winch system adds an automatic recovery demand for unmanned submersibles,the new characteristics of the initial impact of unmanned submersibles on the winch bring significant risks to the safety of the winch.In order to improve the safety of the winch,the finite element dynamic simulation technology of cable is innovatively introduced through the analysis of different wave impact modes,and the corresponding ocean winch model is established.Based on simulation analysis of the dynamic characteristic curves of the tension of the winch cable,the speed of the winch drum,and the negative acceleration of the supporting equipment under different impact directions before and after the installation of the wave compensation equipment,it is concluded that the vertical direction impact improves the efficiency of the system cable load and the negative acceleration of the unmanned submersible by more than 46%compared with that of the horizontal direction impact.An optimization and improvement plan for the winch system is proposed,which can provide an analytical and research means for the safety design of the entire vehicle.
