一种海上换乘系统缆力计算方法

A Method for Calculating the Line Tension of a Transfer System at Sea

本文对一种海上密闭式伤员换乘系统在风、浪、流中缆的受力提出了一种工程计算方法，将缆的三维受力问题简化为水平面和垂直面内的两个二维问题求解，其中垂直面内的二维问题用悬链线近似，而水平面内的二维问题则用准静态方法迭代求解。所得结果供该系统的设计和使用时参考。

This paper presents method for calculating the line tension of an injured person transfer system in wind,wave and current (or forward speed). The 3-D problem for solving the line tension is simplified to 2-D problems in vertical and horizontal planes respectively. The line profile is represented as a catenary in the vertical plane, while in horizontal plane, the line tension problem is solved by quasi-steady method in which the Lunge-Kutta method and an iterative scheme are used. Some results are given. The calculated results can be used in the designing and operational process of the system.
