介绍了快速傅里叶变换在爆破振动预测中的应用,主要包括以傅里叶变换为基础进行的数据采样及将采样所得的数据用Matlab作为工具从时间域转换到频率域,在频率域进行预测后在反变换至时间域即可得到的时间域的预测结果,上述方法已在实验室实现。
This paper introduces the application of fast Fourier transform in blasting vibration prediction, including the data sampling based on Fourier transform and the data obtained by sampling are converted from the time domain to the frequency domain by using Matlab as a tool, in the frequency domain The predicted results in the time domain obtained after the inverse transform into the time domain have been implemented in the laboratory.
