Abstract


, Along with the extensive use of the marine, submarine cable laying project in the development of the whole ocean, use play an important role, at the same time also more demand for submarine cable laying technology. Our traditional paving method not only technical security risks, and laying costs is high, therefore, the study design safe and economical submarine cable laying equipment imminent. In this paper, the main problems can not be achieved when domestic submarine cable laying back twist, combined with the actual project - laying of submarine cables turntable system developed depth study of the the turntable system design problem, including turntable slewing ring mechanism, drive system and the design of control systems and other issues. This paper presents the design of the submarine cable laying dial, and design a key part of the structure of the laying of submarine cables turntable. The research focuses on four aspects: (1) the overall design of the turntable system of submarine cable laying; (2) Slewing mechanism design; (3) three-dimensional model and analysis; (4) the design and simulation of hydraulic control system. The paper discusses in detail the development status of the laying of submarine cables turntable at home and abroad, the key part of the dial, analysis and design calculations to determine the design parameters of the drive system; proposed on the basis of all kinds of slewing ring structure back using double form of roller slewing ring program, the structure of the program is the high life, carrying capacity, rotary resistance is small, and do not ask to install the chassis, as well as withstand the overturning moment. Submarine cable laying dial system using three sets of hydraulic motor drive system synchronous drive, select a low speed, high torque piston hydraulic motor driving torque has been calculated. Use of PRO / E software article turntable system for three-dimensional modeling, finite element model using ANSYS software, the operating conditions of the exposure and the typical load on the ring gear and pinion meshing roller and ring gear The stress analysis. Turntable hydraulic control system, the overall design, including its system components and the design of the control, further disturbing moment under the analysis of control systems performance, computer simulation results are given to verify the effectiveness of the system design. Finally, the existing design issues are summarized submarine cable laying turntable needs to do further work. Through the laying of submarine cables turntable design, provide a compact structure, stable and reliable mechanical system, and accumulated a wealth of design experience in all aspects of the system, and provides information for the optimization and improvement work.
