摘要 应用Wolf方法计算了斜拉桥拉索风雨诱导振动系统的Lyapunov特性指数谱,并分析了多个参数变化对Lyapunov特性指数的影响。从而得出该系统存在动力学混沌现象。并将初始条件作非常微小的改变,计算出系统的相轨线与时程曲线随时间增长差距越来越大,使得长时间无法预测,从而诠释了该系统中的混沌现象。 Wolf's method is utilized to compute Lyapunov-exponent spectra of rain-wind induced vibration model of cables on cable-stayed bridge. The effects of the variety of parameters on Lyapunov exponents are analysed. The conclusion that there exist chaotic phenomena can be drawn.
