Co-Simulation of Running Mechanism System of Bridge Crane Based on Electromechanical Coupling Model

Based on Lagrangian equation, the dynamic equation of load deflection system is established, the process of load deflection is theoretically analyzed, and the electromechanical coupling model of bridge crane is established, This method is used for starting and stable operation The dynamic working process of traveling and braking is numerically simulated, and the variation of yaw angle under different lifting heights, different lifting weights and composite working conditions is analyzed. The results show that the operation of the lifting load lags behind the operation of the lifting trolley, and the relative position of the lifting load and the trolley affects the initial swing angle. The lifting height is an important factor affecting the load deflection, which determines the maximum swing of the load deflection. The deflection of the lifting weight is positively related to the quality of the lifting weight.
