CFRP 斜拉索与钢索风雨激振振动特性对比研究
A Comparative Study of Wind-rain-induced Vibration Characteristics of the CFRP Cable and the Steel Cable
摘要
Abstract
In order to investigate the wind-rain induced vibration characteristics of the carbon fiber reinforced plastic (CFRP)cable,field observations and the results of wind tunnel tests were presented.Based on the aerodynamics,the cable dynamics was calculated.The exciting incentive theoretical basis and the wind-rain-induced vibration mechanism were explored through numerical analyses.The influence of the main parameters for cable vibration was discussed.A comparison was performed between the results from the CFRP cable and the steel cable.Both the axial stiffness criterion and strength criterion cable were used for model establish-ment.It shows that the cable wind-rain vibration has relationship with wind speed,waterline amplitude and damping ratio.At the same condition,the CFRP cable that was designed according to the strength criterion has a better performance in suppressing wind-rain vibration.关键词
