环境参数对浮箱系泊系统水动力性能影响

环境荷载对系泊系统受力和运动响应起着关键的影响作用,有必要对影响系泊系统的关键环境参数进行深入研究,揭示环境参数对系泊系统的作用和影响机理。基于势流理论,结合大型水动力学软件AQWA,以一种简单的矩形浮箱式结构物为典型示例,根据浮箱基本参数及相关技术要求,考虑张紧式和悬链式两种不同的系泊方式,建立系泊系统动力分析计算模型。结果表明:在讨论范围内,系泊力随着流速、流向、风速等环境参数的增加而增加;对于横荡和横摇,随着流速、风速等环境参数的增加,横荡和横摇曲线呈现增加的趋势;相对而言,张紧式系泊可以更好地保持系泊系统稳定。

Effects of environmental parameters on hydrodynamics performance of buoyancy tank mooring system

Environmental load plays a key role in the force and motion response of mooring system.It is necessary to research the key environmental parameters of the mooring system,and reveal the environment parameters on the effect and influence mechanism of the mooring system.Based on the potential flow theory,combined with the large water dynamics software AQWA,we take a simple rectangular pontoon structure as the typical example.Based on the floating body,related technical requirements and basic parameters,we establish mooring system dynamic analysis calculation model by the tension and catenary two different ways.The results show that within the scope of the discussion,mooring force increases with the increase of wind speed as the flow velocity and flow direction.For transverse oscillation and roll,with the increase of environmental parameters such as flow rate,wind speed,swaying and roll curve show increasing trend.The tension mooring type can maintain stability of the mooring system better.
