Further Explanation on the Excitation Mechanism of Stay Cable Vibration in Dry Conditions

The present article outlines a research investigation carried out in wind tunnel setting aimed at augmenting comprehension of the excitation mechanism stay cable vibration arid conditions. A multitude experiments were thoroughly scrutinized. study commenced by conducting measurements conditions steady flow. flow angle was set 45 degrees, and inclination 25 degrees. velocities varied during experiment. Additionally, an into field surrounding cable’s conducted both vertical horizontal directions. By utilizing two hot wire anemometers wake, extensive database obtained. experimental results revealed that characteristics under considered this aligned with findings reported existing literature. Notably, deeper dry state attained. This is closely associated inhibition Karman vortices development low-frequency vortices. At low speeds, predominated, resulting small-amplitude vibrations. However, as speed increased, influence diminished progressively, while grew stronger. These exhibited high energy significant correlation shedding along cable, thereby inducing environment.
