| 摘 要： | 通过某矿山测试所得的爆破震动信号,应用的希尔伯特—黄(HHT)分析法,提取具有实际物理含义的IMF分量,得出爆破震动信号的Hilbert能量谱。分析出该爆破震动的主要频率集中在低频段,从Hilbert能量谱可以直观看出信号能量在时间、频率上的分布情况,这对爆破震动的安全控制具有指导意义。

| Abstract: | The blasting vibration signals of a mine were analyzed by HHT method, the IMF components with practical physical meaning were extracted from the original blasting vibration signals, and the Hilbert energy spectrum was obtained. It proves that the frequen- cy of blasting vibration signals concentrates in low frequency band. The distribution of signal energy by time and frequency can be intuitively observed from Hilbert energy spectrum. It will be a guidance for controlling blasting vibration safely. |
