摘要：
Study on influence of wind induced vibration of tower on Carmen vortex shedding and aerodynamic characteristics is very important for resonance prediction and design of towers. A numerical simulation of the aerodynamic characteristics of the tower vibration is carried out. The non-regular flow around the tower is simulated based on the N-S equation and Transition SST to get the distribution of the pressure coefficient on the outside of the tower. The results of the numerical simulation are compared with the experiment data to verify the accuracy of the numerical simulation method. Then the vibration of the tower is reduced to sinusoidal motion which could be completed by using spring dynamic grid. The regularity of the aerodynamic characteristics such as lift coefficient, drag coefficient and vortex shedding frequency under different oscillating frequencies and displacements of the tower are analyzed.. The influence of the aerodynamic characteristics on the resonance prediction of the tower is discussed based on the resonance condition of the tower. © 2018 Journal of Mechanical Engineering.
