船用起重机吊盘式机械防摇系统的设计与试验

由于风、浪、流、涌等多种海洋环境载荷的影响,船舶会产生横摇、纵摇、艏摇、横荡、纵荡、升沉六自由度运动,船舶的这种基座扰动进而会导致吊重产生大幅度摇晃。针对该问题,提出一种吊盘式机械防摇方案,并搭建船用起重机吊盘式机械防摇系统实验台开展验证实验。通过多组对比实验验证了方案可行性,得到船用起重机吊盘式机械防摇系统对于不同绳长、不同基座运动条件下的吊重摆角时变曲线。实验表明：在无减摇控制时,主吊索的面外角最大值达到13.6°,面内角最大值达到15.5°；而有减摇控制时,主吊索的面外角最大值仅为1.2°,减摇效果达到90%以上,面内角最大值仅为5.9°面内角减摇也达到60%以上。

Anti-swing mechanical design and experimental researchofship-mounted crane

Under the influence of marine environment such as wind, wave and current, the hoisting of ship cranes will cause severe swings, which will affect the normal operations and lead to accidents. In order to solve this problem, a disc type mechanical anti-swing platform is built on the base of the anti-swing theory. The performance of the design scheme is verified by multi group contrast experiments, therefore the anti-swing effect of the platform with different rope length and different form of motion is proved. The result shows that the maximum out-plane angle of the main sling is over 13.6 degrees and out-plane angle is over 15.9 degrees without anti-swing control. But after the anti-swing control has been put into work, the maximum out-plane angle of the main sling is just 1.2 degrees, anti-swing effect is over 90%. In addition, in-plane angle is 5.9 degrees, anti-swing effect is more than 60%.
