摘要:
文章针对爆破振动频谱分析中谱峰值的准确位置不易确定，频带能量分布特征难以直观显现的问题，利用信号处理中的窗函数，采用滑动平均法对爆破振动功率谱进行平滑化，实现了爆破振动频带范围和频带能量分布的直观显现。进一步研究表明，在对功率谱进行平滑化的过程中，可以采用关窗法来进行窗函数带宽的选择，保证既不丢掉功率谱原有的趋势特点，又能很好地将重要的峰点凸现出来。
Abstract:
To study spectrum analysis of blasting vibration, the accurate peak point can not be identified easily during spectrum analyzing. So based on moving average method, the power spectrum of blasting vibration is smoothed by the use of the window function, in order that the frequency band range and energy attribution of blasting vibration can be displayed intuitively. Further research shows that Close-Window-Method can be used to choose the applicable band width of the window function.
