Abstract By wind tunnel tests, cable altitude, rainfall intensity, wind velocity effects on rain-wind induced vibration of cables on cable-stayed bridge were studied. Set cable model when it got the largest vibration amplitude, the two parameters, helical line diameter and twine space, effects on rain-wind induced vibration of cables were studied, and aerodynamic drag force coefficients of cable with different helical line were measured in different Reynolds number range. Results show that for cable model with diameter of 155mm in this research, under the parameters composing of horizontal angle 35°, vertical angle 25°, small rainfall intensity (10mm/h) and certain wind velocity (non-dimensional wind velocity 60~100), cable vibration gets the largest amplitude. Fix the twine space of helical line, vibration control effect trends to evident when the diameter increases; and fix the diameter of helical line, when the twine space decrease the vibration control effect trends to evident. The aerodynamic drag force coefficient of cable with helical line increases, when helical line diameter increases or the twine space decreases. The optimization design rule of helical line was pointed out.
