本文在对国内外斜拉索振动控制研究与应用现状进行综合评述、分析的基础上，针对上述问题进行了深入研究，具体的研究内容和取得的成果包括： 1 、建立了斜拉索-阻尼器系统运动方程，对拉索与桥面的耦合振动作了分析和研究，数值结果显示当桥面激振频率等于某阶拉索模态频率的两倍时，很小的初始扰动将引起拉索的大幅振动，并呈现拍振的特征，与实测的拍振信号一致。 | | 4. | Stay cables of the long - span cable - stayed bridges are susceptible to vibration under wind loading , or wind incorporated rain excitation , or deck motion due to high flexibility , relatively small mass and very low inherent damping , such as vortex shedding , wake galloping , parameter resonance and wind - rain induced vibration . large - amplitude vibration of cables may reduce the life of cables and threaten safe traffic , and has been considered today as one of the most critical problems for this type of bridge
大跨度斜拉桥拉索具有较小的质量和极低的阻尼，在风、风雨及桥面振动等外部激励下极易发生振动，如涡激共振、尾流驰振、参数共振和风雨振等，拉索的大幅振动对拉索的使用寿命和桥梁安全运营构成极大威胁，它已成为大跨度斜拉桥急需解决的关键问题之一。 |
