| Research Abstract |
A container carrier handles cargo containers using onshore container crane. Positioning and swing suppression control is important for cargo-handling efficiency and the suspended container has been modeled as a traveling lamped mass pendulum to develop the control technique. However recently, rotational vibration troubles cargo-handling efficiency. Therefore, in this paper to analyze properly swing-rotation coupling motion, the container is modeled as a rectangular rigid body suspended by four ropes from the trolley, traveling to the target position. The motion is controlled using trolley with feedback traveling and an inertia rotor mounted on the container head block. Eccentric loading inclines the suspended container, since the hoisting drum far away from the trolley needs long hoisting rope length and then the suspending rope is easy to stretch. The experimental and simulation results show that rotational vibration of suspended container relates with swing vibration caused by trolley traveling and also with eccentric loading. Positioning and swing-rotation vibration suppression can be controlled using trolley feedback traveling and inertia rotor.
