FSI Research on the Noise Barrier of High-Speed Railway in the Composite Conditions

Abstract:

Based on the model, it firstly gets the fluid distribution of noise barrier of high-speed railway, which is under the action of train-induced impulsive wind pressure and natural wind load, then transfers the computed result as exported load to the structural analysis module through the coupling interface, by proceeding the transient dynamic analysis and modal analysis, it finally obtains the equivalent stress, total deformation and modal distribution of noise barrier. The results indicate that, compared with train-induced impulsive wind pressure, the natural wind load has a more obvious effect on the structural performance of noise barrier, and its natural frequency is much less than the external load’s, so there will be no resonate happen in practice.
