- 小波分析本质上是一门分析学科,属于时频分析的一种,是傅里叶变换发展史上里程碑似的进展,Meyer认为小波分析是人们对变化敏感体会的一种方法,正如我们对速度的反应一样,身体及大脑仅对加速度有反应,而对速度没感觉。只要火车或飞机的速度是常数,我们就感到它们没有动,这就是小波分析的基本思想,它与人类体验反应、思维方式、视觉工程等十分类似,小波分析的这一特性便于我们区分信号的敏感部分和平坦部分,实施对信号的分析和检测。-wavelet analysis

基于改进的希尔伯特振动分解的机械故障诊断方法研究
- 针对多分量机械故障振动信号的特征提取问题,介绍一种基于希尔伯特振动分解( HVD) 的时频分析方法。该方法首先利用 Hilbert 变换得到原始振动信号的解析信号,然后通过对解析信号的瞬时频率低通滤波获得信号中幅值最大分量的瞬时频率,同时经同步检测获得相应的瞬时幅值和初相位,最后经过迭代运算自适应地检测出原信号各分量的时频信息。针对 HVD 方法的边界效应问题,提出一种基于相关系数准则的波形匹配边界延拓法对其进行改进。 通过两组仿真信号分析验证了 HVD 方法对多分量非平稳信号的分解能力,同时
