【摘要】：通過對工作水深為1 500 m的新型復合式錨泊線進行動剛度和動張力計算,并與靜剛度下計算結果比較,說明了在合成纖維纜的數(shù)值計算中考慮其動剛度特性的必要性;傳統(tǒng)動剛度計算中將整條纖維纜作為直線考慮,假定纖維纜上應力和應變處處相同,不考慮纖維纜自身重量,且忽略流體動力的作用,這些假設和忽略降低了計算精度,且無法適用于不均勻纜和復合式錨泊線的計算;基于集中質量法建立了復合錨泊線的動力學模型,提出基于統(tǒng)計的方法計算合成纖維纜各纜段的平均張力,采用分段動剛度的方法通過迭代求解各纜段上的動剛度和動張力,并考慮了自身重量、流體動力和海流的影響。
[Abstract]:The dynamic stiffness and dynamic tension of a new composite mooring line with a working depth of 1 500 m are calculated and compared with the calculated results under static stiffness. It is necessary to consider the dynamic stiffness of synthetic fiber cable in numerical calculation. In the traditional calculation of dynamic stiffness, the whole fiber cable is considered as a straight line. It is assumed that the stress and strain on the fiber cable are the same everywhere, the weight of the fiber cable is not considered, and the effect of hydrodynamic force is ignored. These assumptions and neglects reduce the accuracy of calculation and can not be applied to the calculation of non-uniform cable and compound mooring line. Based on the lumped mass method, the dynamic model of composite mooring line is established, and the statistical method is proposed to calculate the average tension of each segment of synthetic fiber cable. The piecewise dynamic stiffness method is used to solve the dynamic stiffness and tension of each cable segment iteratively, and the effects of its own weight, hydrodynamic force and current are considered.
