Research on Bridge Crane Rocking Model under Accidental Loads
Establishment of an accurate mathematical crane model is the basis for study of its anti-sway control strategy.This paper constructs a mathematical model for the sway of an overhead crane under accidental loads,analyzes the stress situation of the bridge crane during a working cycle and the operation of large and small vehicles,and builds a three-dimensional dynamic mathematical model during the operation of the bridge crane under the full consideration of accidental loads.The simulation analysis of the model under the action of driving force and wind load is conducted,and the change law of the swing angle of the bridge crane is studied.The swing angle model of bridge crane under accidental load and its variation law provide a theoretical basis for the anti-sway control of subsequent bridge cranes and guarantee the safety and reliability of the bridge cranes underthe action of accidental loads.
