Abstract
Notice of Retraction
After careful and considered review of the content of this paper by a duly constituted expert committee, this paper has been found to be in violation of IEEE´s Publication Principles.
We hereby retract the content of this paper. Reasonable effort should be made to remove all past references to this paper.
The presenting author of this paper has the option to appeal this decision by contacting TPII@ieee.org.
This paper proposed a modified Fast Fournier Transformation algorithm of the difference evolution to solve the problem of inaccurate result for analyzing roll eccentricity signal by FFT. Firstly, the basic principle, realization process and pertinent algorithm program were realized. Then the algorithm had been tested. The simulation results have shown that first-harmonic and harmonic components of eccentricity force signals can effectively analyzed by the MFFT of the difference evolution under conditions that sampling duration is not to the integral multiple of the signal fundamental periodicity. The result demonstrated that the eccentricity influence of the first stand is the most serious and the eccentricity influence of the fifth stand in five-stand cold tandem mill is second. Furthermore the effect of watermarks before hot rolling was the primary factor of periodical rolling force variation. This algorithm is valid for the qualitative analysis and on-line control and compensation of the roll eccentricity.
