双船浮吊系统在不规则波作用下动力响应研究

摘要

Because the random wave induced motion of floating crane can produce substantial swing of the hanging cargo,a dynamic model of hoisting system was established in this paper.The dynamic response of floating crane system in the irregular waves was analyzed.The influences of wave height,wave direction,dipping speed and the ratio of length between wave and hull on swing angle and sling tension were demonstrated.Conclusion obtained from this paper can be used for cargo swing prediction and manipulation,as a reference for the designers.%基于起重船在风、浪、流等载荷作用下会引起吊物的大幅度摆动,通过建立吊物系统的动力学模型分析浮吊系统在不规则波作用下的运动响应,研究波高、波向、吊放速度以及波长与船长之比等因素对吊物摆角与吊索张力的影响.得到的结论可用于吊物系统摆动的预测与控制,可供设计者参考.
