中文摘要：
拉索风雨激振是一种在风雨共同作用下发生的拉索大幅低频振动,现有人工降雨风雨激振试验无法准确模拟自然降雨的多种特性,难于实时再现风雨介质耦合环境拉索气动失稳现象。开发高精度人工降雨模拟装置,可对降雨强度进行精细连续调节,较为准确模拟雨滴大小、能量、均匀度等自然降雨的特性,合理地再现风雨联合作用条件下拉索风雨激振过程;系统研究风速、雨量以及风雨联合作用对拉索风雨激振的影响,揭示了拉索在低风速大雨量、高风速小雨量时,风雨激振发生规律和特点。
英文摘要：
The rain-wind induced vibration（RWIV） with wind effect is a type of vibration of stay cables with large amplitudes.The current artificial rainfall could not simulate the characteristics of natural rainfalls precisely and could not realize the coupling effect in real-time.A high precision artificial raining machine which can precisely simulate the size of droplets,intensity,energy and uniformity of natural rain was developed with a wind tunnel facility.The phenomenon of RWIN of a cable model was successfully re-produced under the condition of rain and wind.The wind speed,rainfall and the coupling effect were systematically investigated.
