摘要

Under complex sea conditions, missiles are susceptible to movement and rotation in multi-degree-of-freedom during carrier-based aircraft replenishment operations on ships, which significantly impacts the efficiency and safety of process. To investigate the dynamic response of the shipboard replenishment system under wave excitation, this paper establishes an accurate dynamic model of the missile lifting and replenishment system, validated through comparative experiments. Subsequently, numerical simulation methods are conducted to analyze the ship’s roll, pitch, and combined roll–pitch motions induced by waves under sea levels 4–6, and to determine the dynamic response of the missile during suspension and lifting process. The results reveal that the higher sea level leads to the greater the dynamic response of the missile’s swing. Furthermore, compared to isolated roll or pitch motions, the combined roll–pitch motions generate a larger amplitude of dynamic response and exhibit more significant nonlinear characteristic in the system’s behavior. The dynamic model proposed herein lays a theoretical groundwork for advancing dynamics and control of floating base cranes.
