| 摘 要： | 简单介绍了重排时频分布,包括Cohen类分布的重排和Affine类分布的重排。并选择属于重排Cohen类分布的平滑伪Wigner-Ville分布重排对地下和露天爆破振动信号的时频特征进行对比分析,得出了它们之间的不同之处和相似之处,以便采取更加合理的措施来减小爆破振动的危害,从而保护地下工程和露天工程设施的安全稳定性。

| Abstract: | The reassigned time-frequency distribution was introduced simply,including Cohen-reassigned and Affine-reassigned distribution.Reassigned smoothed pseudo Wigner-Ville distribution belonging to Cohen-reassigned distribution was selected to compare the time-frequency characteristics of the underground engineering and open-pit blasting vibration signals.The difference and similarity between them were found out,so that reasonable measures would be used to reduce the damage of blasting vibration to protect the s... |
