Abstract: The research on stress distribution of rotating machinery bearing bolts is of great significance for improving the safety, reliability and economy of rotating machinery. In order to overcome the problems of high relative error rate of stress measurement, low analysis accuracy and long time consumption in traditional methods, a research method of stress distribution of rotating machinery bearing bolts based on finite element analysis is proposed. The data of rotating machinery bearing bolts are collected, and the missing data are filled by MIC-LSTM. The finite element model of rotating machinery bearing bolt is established by finite element software, and the stress distribution of bolts is analysed through the steps of material property definition, mesh division, boundary conditions and load application. The experimental results show that the maximum relative error rate of stress measurement is 3.7%, the maximum analysis accuracy is 97.1%, and the average analysis time is 0.45 s.

Keywords: finite element analysis; rotating machinery bearing; bolts; stress distribution; MIC-LSTM; stress measurement.
