Abstract

In this paper, discussions were made on using DFT and IDFT to calculate the transient acceleration response of a single degree system. Two key points were discussed: the sampling frequencies and the time span. Simulation were made the transient response of a single degree system´s transient response, it was found that the sampling frequencies have the greatest influence on the calculation error. The calculation precision´s relation with the sampling frequencies were discussed, it shows that to keep calculation error in 10%, 99% energy in the low frequency should be calculated correctly.
