摘要
基于MOSES软件建立多分舱箱式气浮结构数值模型并模拟多种系泊布置方式,对气浮箱的纵荡、纵摇及垂荡进行时域分析,研究系缆点位置、锚链数量、抛锚方式,以及分舱数对气浮箱运动响应的影响.结果表明,系缆点位置、锚链数量、抛锚方式,以及分舱数量会影响结构运动响应,系缆点位于箱顶、8 根锚链交叉抛锚是最有利的系泊布置方式,增加分舱可以在一定程度上减小箱式气浮结构的运动响应.
Abstract
The numerical model of an air-floating caisson with multiple compartments was established by MOSES software and various anchoring methods were simulated.The time domain analysis of the surge,pitch and heave of the air flotation caisson was carried out.The influence of mooring point position,number of anchor chain,anchoring methods and number of compart-ments on the motion response of an air-floating caisson were studied.The results showed that the position of mooring points,the number of anchor chains,the way of anchoring and the number of compartments will affect the motion response of the structure.The most favorable mooring arrangement mood is that the mooring points are located on the top of t an air-floating caisson and 8 chains and cross anchoring mode.The increase of subdivision can improve the air floating stability of the box type air floating structure to a certain extent.Increasing the number of compartments can reduce the motion response of an air-flotation caisson to a certain extent.
