Improved Real Time Amorphous PV Model for Fault Diagnostic Usage

论述了小波包分解及其能量谱处理发动机连杆轴承故障的原理与方法, 结合传统断火诊断法的思想,应用小波包能量谱直观地识别出故障的特征频带, 并进行量化分析, 结果证明了这种方法比传统的付立叶分析方法具有更大的优越性及现实的应用价值-Discussed and wavelet packet energy spectrum processing engine connecting rod bearing failure principles and methods, combined with trad

基于多层前向网络的诊断模型在设备 故障诊断领域应用比较广泛。 但在多层前向网络的 设计和训练问题上, 单隐层的隐层单元数选取一直非常困难, 一般采用试凑 法, 既费时又 不一定保证收敛。-Diagnostic model based on multilayer feedforward networks in the field of equipment fault diagnosis used widely. But before multilayer design and training
