Coupled Wind-Induced Vibration Analysis of the Membrane Structure Based on Steady-State CFD


Article Preview

Because of large flexibility and strong geometric nonlinearrity, the time domain method should be applied in the analysis of wind-induced vibration for the membrane structure, and the coupling effect between the structure and the fluid should also be considered. In this problem, it is hard now to solve it directly using the technique of three-dimensional transient FSI based on CFD. So in the article, a compromise schedule is proposed, i.e, for the mean wind part, the steady-state FSI technique is applied to solve the parameter such as the mean pressure coefficient, the mean wind velocity, etc, while for the fluctuating wind part, the time integral method is used based on the stochastic function of the wind velocity formed by auto regressive method. The aerodynamic damping is considered in the solving of fluctuating part and five computing schedule are compared, result shows that it is better to use positive mean wind damping for the nodes. It is also suggested that the stochastic wind velocity functuion can be revised based on the kinetic energy distribution of the reference points. A comparison between the computing and testing results show that it is greatly improved for the fluctuating response distribution of the structure.
