Description: 该代码针对滚动轴承故障振动信号呈现出非线性、非平稳性及噪声背景较强等特点,为了有效提取故障特征,使用的一种共振稀疏分解(Resonance-based sparse signal decomposition,RSSD)与小波变换相结合的振动信号特征提取技术的相关仿真实验程序和轴承数据分解程序。其中,共振稀疏分解是基于品质因子可调小波变换与形态分量分析的一种新的信号分解方法,与常规的基于频带划分的信号分解方法不同,它依据信号各分量的振荡形态不同对信号进行分解。 同时还提供了可调谐 Q 因子小波变换 (TQWT)工具箱,TQWT 是类似于理性扩张小波变换(RADWT),但 TQWT 不要求伸缩因子是合理的。 同时也提供了MATLAB遗传算法工具箱Genetic Algorithm Toolbox的相关程序以及使用说明。 -In order to effectively extract the fault characteristics, a resonant sparse decomposition (RSSD) is used to compare the characteristics of the wavelet transform with the wavelet transform phase. In this paper, the resonant vibration signal of the rolling bearing is characterized by non-linearity, nonstationarity and strong noise background. Combined with the vibration signal feature extraction technology related to the simulation of experimental procedures and bearing data decomposition program.
