| 摘 要： | 在理论分析的基础上,研究了利用DFT在频域计算振动烈度的方法,并结合实践经验,给出了实际应用中的注意事项。在频域计算振动烈度,对振动信号类型和计算频率范围选择具有较强灵活性,避免了在时域利用微积分进行信号类型转换和选频滤波等处理过程。

| Abstract: | Based on theoretic analysis,the arithmetic of vibration severity using DFT is investigated,and precautions in actual application are given in combination with practical experience.Vibration severity calculated in frequency domain has strong flexibility for the vibration signal style and frequency range selection,which can avoid signal conversion by calculus and frequency select filter in time domain. |
