摘要

用新的理论和方法丰富和提高机械故障诊断技术是机械故障诊断学的重要内容之一。本文用约束独立成分分析方法把研究对象的先验信息作为独立成分分析算法的约束条件，使新的算法仅仅收敛于感兴趣的故障信号。这样可以提高故障诊断的针对性和效果。该方法可以从传感器信号中快速诊断设备中是否发生了某种故障，并以滚动轴承的仿真和实验验证了该方法的适用性和有效性。

Abstract

It is very important and necessary for mechanical fault diagnostics to enrich and improve machine fault diagnosis technology. The prior information of the object as a constraint is integrated into the independent component analysis algorithm based on constrained dependent component analysis and the new algorithm converges only fault signal of interest in the paper. The relevance and effectiveness of fault diagnosis are improved. The method can find out rapidly whether there is a fault in mechanical equipment from sensor signals. The applicability and effectiveness of the method are verified by the simulation and experiment of roll element bearing.
