【摘要】：采用局部极值步长法和峭度准则,实现了形态学运算结构元素的自适应选择。改良了基于广义形态学闭开差值运算的相关算法,改善了获取轴承弱故障特征的效果。仿真信号及实测故障振动信号的分析表明,所提出诊断方法的诊断效果优于传统的广义形态学分析方法,该诊断方法能够较准确地提取滚动轴承微弱故障特征。
[Abstract]:The local extremum step size method and kurtosis criterion are used to realize the adaptive selection of structural elements in morphological operations. The algorithm based on the closed difference operation of generalized morphology is improved, and the effect of obtaining the weak fault feature of bearing is improved. The analysis of the simulated signal and the measured fault vibration signal shows that the diagnostic effect of the proposed method is better than that of the traditional generalized morphological analysis method, which can accurately extract the weak fault characteristics of rolling bearing.
