摘　　要：为给木工带锯条在线故障诊断提供技术依据,利用时间序列分析理论和Eviews 8.0软件,系统分析MJ3210型跑车木工带锯机产生裂纹缺陷后的带锯条横向振动位移数据;建立时间序列模型,预测、分析裂纹扩展下带锯条的横向振动位移变化,得到与实际数据比较吻合的结果.研究结果充分说明时间序列分析可以成为带锯条裂纹研究与预测的一个新方法.In order to provide technical basis for on-line fault diagnosis of woodworking band saw blade,we use time series analysis theory and Eviews 8.0 software, the data of the lateral vibration displacement of the band saw blade after the crack defects of the MJ3210 sports car sawing machine are analyzed systematically. A time series model is established, and the lateral vibration displacement of the band saw blade under the crack propagation is predicted and analyzed ,we get the results consistent with the actual comparison,which fully shows that the time series analysis method is also a new method of research and prediction of band saw blade crack.
