| 摘 要： | 研究两个自由度的斜拉索风雨激振模型,利用符号代数语言Mathematica对系统进行数值分析,得到了索结构和水线的运动相图,结果表明他们的运动均收敛于稳定的极限环。同时分析讨论了拉索结构阻尼、风攻角等因素对系统运动的影响。 |
| 关 键 词： | 风雨激振 拉索 非线性 水线 阻尼 |

| Abstract: | Two-degree model of rain-wind-induced vibrations of cable structure was studied.The original system was studied by numerical computation with symbol algebra language mathematica.The phase diagrams of cable and water-line were achieved.It showed that their moments converged to limit circles.The influence of damping of cable,angle of attack etc was discussed. |
| Keywords: | rain-wind-induced vibrations cable nonlinear water-line damp |
