海上横向补给系统高架索参数影响分析

在不考虑动载荷影响前提下,基于力学基本原理建立了海上横向补给系统高架索静挠度与张力的表达式,在此基础上,研究了张力、集中载荷、高架索两端高度差、高架索跨距等系统参数对高架索最大静挠度的影响.结果表明,在可控因素中,张力对高架索静挠度影响最大.最后,借助符号运算软件MatIlematica得到了货物沿整个高架索输送过程的运行轨迹,同时利用抛物线极值理论得到了货物输送危险点表达式.

Influence of parameters for highline cable of maritime alongside replenishment system

The static deflection expression of the highline cable of maritime alongside replenishment system in terms of tension was given by classical mechanics theory without considering the influence of dynamic loading. The influence of tension, concentration loading, and the vertical and horizontal distance of the ends of highline cable were studied explicitly. The result shows that tension is the most important among these controllable factors. In the end, the trajectory of cargo along the cable was acquired by symbol algebra language Mathematica. The danger point expression of cargo was given by the extremum principle of parabola.
