    摘要:

    基于三维势流理论,考虑运输船舶对起重船的水动力干扰作用,建立双浮体系统中起重船-吊物的时域耦合分析模型,研究4种系泊方案下起重船与吊物的运动响应,结合系泊缆张力的动态响应,对比分析系泊系统对起重船和吊物的影响。结果表明:起重船与吊物的运动响应具有同步性;当运输船旁靠起重船时,起重船和吊物的运动响应较小,可有效地降低运输船对起重船的水动力干扰。

    Abstract:

    Based on the three dimensional potential flow theory, considering the hydrodynamic interference effect of the transport ship on the floating crane, the time-domain coupling analysis model of the floating crane-lifting object double floating body system is established, the motion response of the floating crane and lifting object under four kinds of mooring schemes are studied, and combined with the dynamic response of the mooring line tension, the influence of the mooring system on the floating crane and lifting object is contrastively analyzed. It is indicated that: the motion response of the floating crane and lifting object is synchronous; when the transport ship is alongside the floating crane, the motion response of the floating crane and lifting object is small, which can effectively reduce the hydrodynamic interference of the transport ship to the floating crane.
