摘要
基于凝集质量法,把高架索系统离散为凝集质量模型,并将缆索间的接触摩擦引入到动态分析中。参考某高架索系统具体参数,结合海上横向补给施工作业的具体过程,通过必要的简化,利用动力学分析软件OrcaFlex建立了海上横向补给高架索系统过程的动力学模型,得到了高架索系统张力及接触力随时间的变化情况等。计算结果对研究海上横向补给有一定的指导意义。
Based on the lumped mass method, the highline cable system is discretized into a lumped mass model. In consideration of the contact and friction of the cables during the dynamic analysis, referring to a highline system specific parameters, combined with the specific process of alongside replenishment operations, by necessary simplification, the dynamic model for the highline cable system at sea is established by the dynamic analysis software OrcaFlex. The tension and contact force changing with time are obtained. The calculation results have certain guiding significance for the study of the alongside replenishment.
