Description

technical field [0001] The invention relates to a dynamic electromechanical joint simulation method of a bridge crane, which belongs to the technical field of crane dynamics and electrical control. Background technique [0002] At present, the co-simulation of virtual prototype is widely used in enterprises because of its short research period, low cost and high efficiency. However, most of the control systems in the research on the dynamics simulation of bridge cranes are driven by functions in ADAMS software, and few Even without considering the mechanical characteristics of the motor, it cannot cope with complex and changeable conditions. Contents of the invention [0003] The purpose of the present invention is to solve the technical problems existing in the dynamics simulation of the bridge crane that does not consider the mechanical characteristics of the motor and cannot cope with complex and changeable conditions, and provides a dynamic electromechanical joint simu...
