摘要

This work presents a study on the dynamics and control of an unloaded hanging chain suspended from an overhead crane, having wind disturbance throughout the entire maneuver. The study focuses on using input shaping via a step function, applied continuously from the start to the end of the maneuver, to eliminate the effects of residual vibration. This research specifically examines the behavior of the chain’s primary modes under the influence of wind. The input function for a flexible chain is determined using a modal model matrix and Laplace transformations while considering wind disturbance effects. This approach shows highly precise control, providing valuable insights into managing dynamic responses in flexible structures suspended from an overhead crane and exposed to external disturbances.
