利用MISEP算法对直升机齿轮箱振动信号的非线性混叠进行了盲源分离,分离出了轴承故障振动信号,并将该方法应用于实际的飞机发动机的振动信号分析,分离结果表明MISEP盲源分离算法是机械故障诊断领域的一个有效的信号处理方法。
In this paper, the MISEP is mainly made use of separating helicopter gearbox signals in the non - linear mixture. The MISEP can separate the bearing vibration signal effectively from other source signals. As the method applying to the actual aero - engine vibration signal analysis, the method can separate actual chaotic vibration signal from the actual aeroengine vibration signals too. The results show that the MISEP was an effective signal processing method in mechanical faults diagnosis domain.
