以起重船在海上起吊作业为背景,建立了吊重系统三维非线性运动学模型。分析了吊重系统在规则波作用下的摆动特性。采用数值仿真软件对时域非线性分析进行求解,讨论了波向、波浪频率以及升降速度对吊重摆角和吊索张力的影响。得到的结论可用于吊重系统摆动的预测与控制,可供设计者参考。
以起重船在海上起弔作業為揹景,建立瞭弔重繫統三維非線性運動學模型。分析瞭弔重繫統在規則波作用下的襬動特性。採用數值倣真軟件對時域非線性分析進行求解,討論瞭波嚮、波浪頻率以及升降速度對弔重襬角和弔索張力的影響。得到的結論可用于弔重繫統襬動的預測與控製,可供設計者參攷。

A three?dimensional nonlinear kinematic model of hoisting system was set up in the background of floating crane lifting operations at sea. The oscillation characteristics of hoisting system under the action of regular wave were analyzed. The time?domain nonlinear analysis was solved with numerical simulation software, discussing the effect of wave direction, wave frequency and hoisting speed on the swinging angle and cable tension. Conclusion obtained from this work can be used for cargo swing prediction and manipulation, as the reference for the designers.
