The four bearings are in the same shaft and are forced lubricated by a circulation system that regulates the flow and the temperature. Compared with the other models, Informer had the best forecasting results, which can not only forecast the trend of data series transformation and extreme values better, but also has less offset. Time Series Analysis: Forecasting and Control. Fault detection at rotating machinery with the help of vibration sensors offers the possibility to detect damage to machines at an early stage and to prevent production downtimes by taking appropriate measures. Part C J. Mech. It had excellent performance in evaluation indexes such as MAE, MSE and RMSE and the forecasting results. Not applicable for studies not involving humans or animals.

Based on the above problems and analysis, in this paper, the Informer model [36] is innovatively introduced into the prediction of motor bearing vibration and a time series forecasting method of motor bearing vibration based on random search [37] to optimize the Informer model is proposed. The vibration signal of the motor bearing obtained by the sensor can reflect the fault characteristics [6,7,8]. Each file consists of 20,480 points with the signal: Looks about right (qualitatively), noisy but more or less as expected. The motor is the core equipment of the power station; therefore, monitoring the motor vibration and predicting time series of the bearing vibration can effectively avoid hazards such as bearing heating and reduce energy consumption. The offset of individual extreme value forecasting is relatively large, so the calculation results of MAE, MSE and RMSE are not as good as these two models. Some tasks are inferred based on the benchmarks list. Nikovski et al. Them in a.csv file name is added to the TV & # x27 ; s history! For datasets of inner race damage (I-I), outer race damage (O-I) and rolling element damage (B-I) under accelerated conditions, compared with other models, the Informer achieved the best forecasting results, as shown in Table 9.
