摘　　要：针对船用起重机的吊重摇摆抑制问题,设计一种船用起重机吊盘减摇装置,利用2根恒张力减摇索和主吊索在吊盘处形成相对稳定的力的三角形,同时吊盘将减小吊绳及吊重的摆幅。建立吊重在有无吊盘下的运动学方程,在Matlab/Simulink软件中对模型进行仿真分析,对比分析在船舶不同的横、纵摇运动角度下有无减摇装置时吊重的摇摆,结果表明,有吊盘的情况下,吊重的摆角可减小70%左右,通过搭建试验平台进行试验,得到有吊盘时,吊重的摆角可减小60.7%左右,验证了减摇装置的有效性。To suppress the swing of the payload, a kind of sling tray anti-swing device was designed, which can reduce the swing of payload by reducing the length of the lifting rope by using two constant force cables with the main cable to establish a rel- atively stable triangle by the sling tray. The kinematic equations of the payload were established under the condition of whether sling tray was provided, and the dynamic was carried out in Matlab/Simulink environment. The swing of the payload under differ- ent rolling and pitching angles was analyzed. The results showed that the swing reduced about 70% payload in the case of the hanging plate. It was well agreed with the experimental result, verifying the effectiveness of the anti-swing device.
