“…Concurrently, in recent years, numerous scholars have undertaken research into the diverse shipborne equipment of helicopter traction systems, encompassing aspects such as aerodynamics [15][16][17][18], multibody dynamics [19][20][21], system reliability [22], and path planning [23,24]. However, presently, the issue of [25] high-energy consumption by the current helicopter traction systems when transporting shipborne helicopters [10,26], presenting substantial stress to the vessel's energy supply system, and the intricate entanglement of traction steps during task execution are underrated. Essentially, both issues are attributed to the utilization of hydraulic components for the power source within the helicopter traction system, resulting in uncontrollable traction movement speed.…”

As countries attach great importance to the ocean-going navigation capability of ships, the energy consumption of shipborne equipment has attracted much attention. Although energy consumption analysis is a guiding method to improve energy efficiency, it often ignores the dynamic characteristics of the system. However, the traditional dynamic analysis method hardly considers the energy consumption characteristics of the system. In this paper, a new type of electric-driven helicopter traction system is designed based on the ASIST system. Combined with power bond graph theory, a system dynamic modeling method that considers both dynamic and energy consumption characteristics is proposed, and simulation analysis is carried out. The results indicate that the designed traction system in this study displays high responsiveness, robust, steady-state characteristics, and superior energy efficiency. When it engages with helicopter-borne aircraft, it swiftly transitions to a stable state within 0.2 s while preserving an efficient speed tracking effect under substantial load force, and no significant fluctuations are detected in the motor rotation rate or the helicopter movement velocity. Moreover, it presents a high energy utilization rate, achieving an impressive energy utilization rate of 84% per single working cycle. Simultaneously, the proposed modeling methodology is validated as sound and effective, particularly apt for the dynamic and power consumption analysis of marine complex machinery systems, guiding the high-efficiency design of the transmission system.
