提出一种改进的P-W串联算法作为提取数据特征矢量的工具,结合人工神经网络算法,建立了米-17直升机的发动机故障诊断模型。仿真结果证实了P-W算法对直升机振动信号处理与诊断的有效性。
An improved P-W tandem algorithm is proposed as a tool to extract the data feature vector. Combined with the artificial neural network algorithm, an engine fault diagnosis model of Mi-17 helicopter is established. Simulation results confirm the effectiveness of P-W algorithm in helicopter vibration signal processing and diagnosis.
