EMD分解盲源分离算法在振动筛故障诊断中的应用

摘要

振动筛广泛运用于工业领域，振动筛故障诊断研究有实际意义。以振动筛轴承故障为例，先估计振动筛轴承故障时的振动源数，再利用基于经验模态分解（EMD）的盲源分离（BSS）算法分析振动筛轴承的故障特征。%The vibrating screen is widely used in industries. The research of its fault diagnosis is possessed of importance. Taking the bearing fault for example, firstly estimates the number of vibrating source of the screen during its trouble, and then analyzes the feature of bearing fault by means of EMD-BSS method.
