Abstract: In the process of lifting and swing reduction, the slender payload presents typical double-pendulum characteristics. In order to solve the difficult problem of swing reduction of slender payload under rough sea conditions, a multi-flexible cable-driven anti-swing system for slender payload is proposed. A dynamic model of the double-pendulum system of slender payload is established by using the robotics and Newton method. The influence of damping coefficient, variable mass and length ratio of hook and slender payload and ship-motion excitation on the anti-swing system is studied. According to the principle of the anti-swing system of slender payload driven by multiple anti-swing taglines, the experimental scale prototype is built. The experimental results show that the simulation curve of the double-pendulum of the slender payload is consistent with the experimental results, which verifies the accuracy of the dynamic model of the double-pendulum system of the slender payload. The research results can provide a basis for the design of the a multi-flexible cable-driven anti-swing system for slender payload, and provide a theoretical basis for the further engineering application.
