摘要：The research on the numerical relations between signal of seismic wave input and output responses is significant for further study of the methods of structural dynamic analysis and the verification of advanced time domain algorithm in frequency domain. Firstly, the condition of equivalence between Fourier transform and trigonometric series is deduced in theory, then an algorithm of trigonometric function is introduced to obtain spectrum of arbitrary frequency excluding the methods of discrete Fourier transform. Considering the dynamic response of damp system, the analytical verification of relations between signal input and output responses in time and frequency domains is carried out. Finally, availability of the trigonometric function algorithm is proved through dynamic response analysis of multiple particles damp system.
