Research on Elastic Dynamic Model of Trolley System for Anti-sway Control System of Bridge Crane

For bridge cranes, the movement of the trolley will cause the vibration of the cart and the vertical deformation of the cranes, including the elastic deformation of the main beam, the elastic deformation of the cart running mechanism and the supporting legs. This paper analyzes the influence of the crane vertical deformation on anti-sway control, presents a novel three-mass three-degree-of-freedom elastic dynamic model of the trolley system when the cart is stationary and only the trolley is running. The validity of the model is verified by Matlab.
