In order to determine the swing angle change of wire rope during operation,this paper analyzes the motion process of bridge crane,establishes a mathematical model,determines that θx and θy are related to the acceleration(deceleration)of crane and trolley,and uses MATLAB software to analyze the influence of the length of lifting rope and trolley acceleration on the swing angle of wire rope;the results show that the swing angle can be controlled by reducing the rope length;it can also restrain the swing of the lifting load by constantly changing the running state of the trolley.
