摘　　要：为了研究柔性连接多浮体结构在波浪作用下所受漂移力大小的问题。本文应用势流模型近场法研究了柔性连接的串联五模块浮式结构在规则波作用下的平均波浪漂移力和不规则波作用下低频慢漂力大小的影响因素。随着模块个数增加,结构所受平均漂移力呈线性增加,平均漂移位移受系泊缆的影响呈非线性增加。不规则波作用工况,低频慢漂力增加,但由于模块间遮蔽效应,结构漂移力呈非线性增加趋势,并且漂移力大小是有限的。随着连接刚度增加,平台结构整体所受平均漂移力减小,连接器刚度变化对低频慢漂力影响相对较小。In order to sutdy the wave drift force on the flexibly connected multi-module floating platforms under wave action.In this study,the potential flow model near-field method is applied to investigate the influencing factors of the mean wave drift force under regular waves and the low-frequency slow drift force under irregular waves of a flexible connected tandem five-module floating structure.As the number of modules grows,the mean drift force on the structure rises linearly,and the mean drift displacement increases nonlinearly due to the influence of the mooring cable.The low-frequency slow drift force increases in irregular waves,but the structural drift force tends to rise nonlinearly due to intermodule shading effects and the finite magnitude of the drift force.As the connection stiffness increases,the mean drift force on the entire structure decreases,and the change in connector stiffness has little effect on the low-frequency slow drift force.
