Table is one set of main equipment for a rolling production line delivery rolled piece, and the bearing failure will lead to line paralysis. To understand and master the operation condition of the bearing and find fault are very important at any moment. By constructing equipment radiation noise field monitoring shock pulse wave, and through analysis of the characteristic frequency and resonance, the technology of intuitive dynamic image noise source identification and positioning was put forward. The rolling bearing fault site is more effectively and more accurately diagnosed,meeting with actual situation diagnosis.
