Analysis of the acoustic response of the SV wave turbine
In order to analyze the impact of seismic waves on site earthquakes under oblique incidence of seismic waves,based on the explicit dynamic finite element method,the viscoelastic artificial boundary is used,and SV waves are obliquely incident on the convex terrain with different slopes,and the ground motion amplification of the convex site under different incidence angles is analyzed.Coefficient and Fourier spectrum changes.The analytical and numerical solutions of the verification model are in good agreement.The numerical simulation results show that with the increase of slope gradient,the amplification factor of ground motion increases,and the amplification factor on the slope changes obviously.The X-direction magnification factor is greater than the y-direction magnification factor.The Fourier curve with a frequency of 0.2～1 Hz increases with the increase of the slope of the convex terrain;when the EI-centro wave is incident at 30°,the amplitude of the Fourier spectrum decreases with the increase of the incident angle in the low frequency band.Small trend,the Fourier spectrum amplitude of the monitoring points in the high frequency band increases with the increase of the incident angle,and the amplitude change rate is the largest in the high frequency band of 1～10 Hz.
