辊道是轧钢生产线上运送轧件的主要设备，其轴承的失效将导致轧线的瘫痪，随时了解和掌握轴承的运行状态并及时发现故障十分重要，通过构建设备辐射噪声场监听冲击脉冲波，经特征频率及共振分析，研究出了“直观的动态图像噪声源的识别与定位”技术，更有效、更准确地诊断出滚动轴承的故障部位，取得了与实际情况完全吻合的诊断结果。
輥道是軋鋼生產線上運送軋件的主要設備，其軸承的失效將導緻軋線的癱瘓，隨時瞭解和掌握軸承的運行狀態併及時髮現故障十分重要，通過構建設備輻射譟聲場鑑聽遲擊脈遲波，經特徵頻率及共振分析，研究齣瞭“直觀的動態圖像譟聲源的識彆與定位”技術，更有效、更準確地診斷齣滾動軸承的故障部位，取得瞭與實際情況完全吻閤的診斷結果。

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 reso-nance,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.
