本发明公开了一种基于CNNBiGRUAM模型的滚动轴承故障诊断方法,首先将外吸附式振动传感器吸附在滚动轴承所在位置腔壁外侧X轴,Y轴外侧,并利用NI9234数据采集卡采集故障轴承振动数据,再采用连续小波变换将故障轴承振动数据处理为二维时频图,增强故障特征提高其鲁棒性;其次构建CNNBiGRUAM诊断模型并参数初始化;最后通过训练理想...
The final stage involves a comparative analysis of the probability values generated by CNN-AM-BiGRU, CNN-BiGRU, and CNN-BiGRU-AM across a specific iteration. This comparison is conducted under two distinct scenarios: one involving FFT preprocessing and the other without it, alongside varying ...
