摘要
Aiming at the variable reflux/DC atmospheric boundary layer wind tunnel in Shijiazhuang Tiedao University, a new test rig for stay cables' rain-wind induced vibration was designed. Its components and working principle were introduced. A series of wind tunnel tests for stay cables' rain-wind induced vibration were performed using this test rig. The effects of rainfall intensity, inclination angle of cable, wind yaw angle and wind velocity on stay cables' rain-wind induced vibration were studied. The test results showed that the designed test rig can meet wind tunnel tests' requirements for stay cables' rain-wind induced vibration; for a cable with a diameter of 155 mm under the conditions of inclination angle 25°, wind yaw angle 35°, rainfall intensity 10 mm/h and wind velocity 13 m/s, its rain-wind induced vibration amplitude reaches the maximum.. © 2017, Editorial Office of Journal of Vibration and Shock.
