The invention relates to the technical field of intelligent control, in particular to a control method for slowing down swinging of a hoisted object of a crown block, the crown block comprises a travelling crane, a steel wire rope and a lifting hook, and the control method comprises the following steps that the swinging period T1 of the lifting hook in movement under the condition that no hoisted object exists and the swinging length Lb of the hoisted object under the condition that the hoisted object exists are obtained in advance; the actual running speed of the travelling crane is controlled to be 0.3 V-V, so that the swing of the overhead crane in the running process is slowed down, # imgabs0 # V1 is the theoretical running speed of the travelling crane under the current power, Q is the height coefficient of the overhead crane, when the travelling crane is in a decelerating state, +/-in a formula (1) is +, when the travelling crane is in an accelerating state, +/-in the formula (1) is-, and g is gravitational acceleration. According to the invention, the actual running speed can be provided for the crown block, thereby slowing down the swinging of a hoisted object below the crown block.
本发明涉及智能控制的技术领域,具体而言,本发明提供了一种减缓天车吊物摇摆的控制方法,天车包括行车、钢丝绳和吊钩,包括以下步骤:预先获取无吊物情况下吊钩在运动中的摇摆周期T1,有吊物情况下吊物摆长Lb;将行车的实际运行速度控制在0.3V‑V之间,从而减缓天车吊物在运行过程中的摇摆,#imgabs0#V1为行车在当前功率下的理论运行速度,Q为天车的高度系数,所述行车为减速状态时,公式(1)中的“±”为+,所述行车为加速状态时,公式(1)中的“±”为-,g为重力加速度。本发明可以为天车提供实际的运行速度,从而减缓天车下方吊物的摇摆。
