摘要
本文提出的计算程序ＣＡＢＬＥ能预报拖缆系统中拖曳线列阵的三维运动，同时可计算各时刻缆索及列阵上相应的应力。系统的运动方程与Ａｂｌｏｗ［１］提出的相似，采用有限差分法计算求解。程序能够计算不同航速定常直航状态下列阵的阵形与姿态，可解决不定常运动（例如回转运动）、考虑流速以及船舶有升沉等多种运动状况的阵形预测。所得结果与其它计算及试验所提出的结果显示出良好的一致性。程序所花计算时间少，计算可靠。程序可运用于实际操作中。
The program CABLE presented in this paper can predicate the three dimensional motion of towed array in towed cable systems. It can also compute the stresses in the cable and array at any time. The equations of motion are similar to those presented by Ablow , and solved by finite difference approximation. The program can compute the array shape and attitude on steady straight runs at different speeds, and solve unsteady motions (for example, loop turn motion) and other motions. The current velocity and ship′s heaving,etc.can be considered. The results of the computation show good agreement with the results presented by other computations and experiments. The program takes little computation time. The results are reliable and the program can be used in practical operations.
