應變測量中干擾數(shù)據(jù)的分析及處理

Analysis and processing of noise data in strain measurement

  • 摘要: 文章闡述了某振動試驗中應變測量的干擾數(shù)據(jù)的分析及處理。主要從應變測量原理及不同測量方式的差異及特點分析了干擾信號產(chǎn)生的根源，提出了解決干擾的方法。同時從掃描正弦數(shù)據(jù)處理理論和方法上對結構響應數(shù)據(jù)中干擾信號的異常現(xiàn)象進行了分析。

     

    Abstract: This paper discusses analysis and processing of noise data in strain measurement during vibration test. The origin of noise data is analyzed according to the measurement principle and different measurement methods. At the end, the paper analyzes some abnormal phenomena in light of sweep sine data reduction.
