摘要:
基于振动检测的发动机故障诊断算法，分析发动机发生故障时振动信号所具有的特征和故障诊断指标选择，对振动信号预处理、特征提取、状态识别和诊断决策分别进行了介绍，研究出采用振幅和频率两参量包络曲线法诊断发动机故障的算法，通过发动机热试车验证了采用发动机振动检测来判断发动机故障的算法的正确性。
Abstract:
A rocket engine fault diagnosis algorithm based on the vibration signal detection is proposed in this paper. The characteristics of vibration signal as the engine fault occurs are analysed. The selection of fault diagnosis indexes, vibration signal pretreatment, feature extraction, state identification and diagnosis decision are introduced respectively in the scheme. The algorithm that adopts the envelope curve method of amplitude and the vibration frequency parameters to diagnose the engine fault was studied. The engine hot test verified the correctness of the algorithm, which adopts the detection method of rocket engine vibration signal to judge the engine fault.
