AI Article Synopsis
- The study examines how wind and operator skill affect the performance and safety of slewing cranes, particularly their swing angles.
- It develops an anti-swing control system using a mechanical setup and fuzzy PID control to enhance operation safety and efficiency.
- Results indicate a significant reduction in swing angles by 88% and 75% for the lifting arm, demonstrating the effectiveness of the proposed anti-swing mechanism.
Article Abstract
Background: The slewing crane is easily affected by the wind and the manipulation level of the operator when it is working, which in turn impacts its swing angle, affects the working efficiency and safety of the crane.
Objective: Toimprove the operation safety andreduce the swing angle, this study design and research the anti-swing control system for the slewing crane.
Methods: Firstly, based on the Lagrange equation, the dynamic model of the crane hoisting system is established. Then, the mechanical anti-swing mechanism driven by a four-motor rope is established. Finally, based on fuzzy PID control, an anti-swing platform is established, and the performance of anti-swing control is verified.
Results: Compared to no anti-swing control, the in-plane swing angle θ1 and out-of-plane swing angle θ2 of the lifting arm are reduced by 88% and 75% respectively.
Conclusion: The results show that the four-motor rope-driven anti-swing mechanism can achieve better anti-swing effect, which provides an effective swing suppression method for the slewing crane in the actual operation.
