Rain-Wind-Induced Vibration of Cable Computed by Ansys

摘要：

　　Stay cable is one of the main components of cable stayed bridge to bear loads.Due to its large flexibility,small quality and small damping,various of harmful vibrations could happen easily under the external excitations.Rain-wind-induced vibration is the strongest form of vibrations.Under the joint action of wind and rain,big vibration will take place.The vibration is relatively complex because the vibration belongs to three-phase coupling vibration.According to the existing water balance equation of rain-wind-induced vibration numerical analysis,the vibration of cable in different wind speed,wind directions and different waterway directions are respectively analyzed,the results show that the rain-wind-induced vibration of cable is greatly influenced by wind directions,and waterway directions has a very significant impact as well.
