An Improved Recursive ARIMA Method with Recurrent Process for Remaining Useful Life Estimation of Bearings

The experimental platform PRONOSTIA. In the accelerated degradation experiment of bearings carried out on the PRONOSTIA platform, the data collected from two mutually orthogonal acceleration sensors are transmitted to the computer through DAQ equipment. In order to accelerate the aging of the bearing, radial force is exerted on the bearing [47].
