基于支持向量机和信息融合的整机振动状态监视与诊断

The Monitoring and Diagnosis of Aeroengine Vibration Based on the Support Vector Machine and Information Fusion

将信息融合和支持向量机等智能诊断技术应用于整机振动状态监视与故障诊断领域。采用航空发动机振动信号作为诊断模型的训练样本,使支持向量机能够反映特征向量和故障类型的映射关系,从而成功地诊断了某型发动机的振动故障模式。

The intelligent diagnosis technology such as information fusion and support vector machine was applied in the aeroengine vibration monitoring and fault diagnosis. Taking the vibration signal as the training samples of the diagnosis model, the mapping relationship between the characteristic vector and fault type can be related by the support vector machine. The vibration fault mode of an aeroengine was successfully diagnosed.
