摘要
依据集中质量法建立缆绳力学模型,分析了浮筒净浮力大小、位置以及海流力对缆绳构型和静态张力的影响程度。研究结果表明:水下浮筒可有效降低系泊载荷与预张力,提高缆绳水平回复刚度,但可能导致缆绳最大张力位置的改变,此外浮筒净浮力与位置均存在最优值,浮筒所承受的海流力对于缆绳静力特性的影响非常有限。
A flexible mechanics model of the mooring line is established according the lumped mass method. The effects of the net buoyancy, location and the current force of the buoy on the static characteristics of the mooring line are analyzed. The result shows that by using submersible buoy, the mooring load and pretension will be reduced, and the horizontal stiffness is improved, but the location where the maximum cable tension appears maybe changed. The buoyancy and location of the buoy exist optimum values, the influence of the current force on the buoy is very limited.
