Application of Time Serial Synthetical Analysis in Experiment on Flexible Forming of Sheet Metal

Wu Wenbin~1,Tang Jingjing~1,Xu Wenji~2,Dong Haixiang~3(1.Henan University of Technology,Zhengzhou 450052,China;2.Dalian University of Technology,Dalian 116024,China;3.North China University of Water Conservancy And Electric Power,Zhengzhou 450001,China)  
A synthetical analysis method combining the analysis method with the grays theory is adopted aimed at the key issue of data management in the experiment on flexible forming of sheet metal using plasma arc.This method is used to describe the change of angle during the process of flexible forming of sheet metal.The actual measurement of angle change demonstrates that it is feasible to utilize GM(1,1) and ARMA mode to describe the forming of sheet metal.At the end,the forecast formula is presented to predict variation trend of the flexible forming.
