船用起重机减摇装置建模与试验

针对船用起重机在吊重摇摆的抑制问题,设计了一种船用起重机吊盘减摇装置。利用恒张力吊盘将吊绳的摆幅减小,从而减小吊重的摇摆。建立吊重在有无吊盘下的吊重的运动学方程,使用MATLAB/Simulink软件对运动学模型进行仿真分析。详细分析了在船舶不同的横摇角度下吊重的摇摆情况,并进行有无吊盘减摇装置的对比。结果表明,有吊盘的情况下,吊重的面内角可减小54%左右,面外角可减小59%左右,通过搭建试验平台进行试验,得到有吊盘时,吊重的面内角可减小60%左右,面外角可减小53%左右,验证了减摇装置的有效性。

Anti-swing device modelling and experiment of ship-mounted crane

To suppress the swing of the payload, a kind of hanging plate anti-swing device was designed, which reduced the length of the lifting rope and the swing of payload by using the constant tension hanging plate. The kinematic equations of the payload were established under the condition of whether hanging plate was provided, and the dynamic was carried out in Matlab/Simulink Simulink environment. The swing of the payload under different rolling angles was analyzed in a comparative manner. The results showed that the in-plane angle reduced 60% and out -plane angle reduced 55% of the payload in the case of the hanging plate. Experiment was carried out, the in-plane angle reduced 60% and out -plane angle reduced 53% of the payload in the case of the hanging plate. The experimental results verified the effectiveness of the hanging plate anti-swing device.
