基于悬链线方程的海上横向补给高架索系统静力学分析

摘要

基于悬链线方程，建立考虑高架索长度和自重变化的海上横向补给高架索线形分析静力学模型，探讨高架索单位长度质量和张力大小等参数对高架索线形的影响，研究发现当高架索水平张力与补给品重量比值大于4时，高架索挠度很小，可以安全输运补给品。%Statics analysis model is established based on catenary equation for alongside-arranged highline cable replenishment system at sea after considering influence of cable’s length and weight. Effects of several parameters, including cable’s unit weight and tensile force, are then discussed. It is found when the ratio of horizontal tension to cargo weight exceeds 4, the deflection of highline cable is ignorable to safely transfer cargos.
