<P>PROBLEM TO BE SOLVED: To detect chattering vibrations generated only by a rolling state by distinguishing between chattering caused by a mechanical state and chattering caused by the rolling state. <P>SOLUTION: The method for detecting the chattering includes the step of analyzing the shape of a FFT transformed frequency wave form by means of a pattern recognition among mill vibrations generated during rolling in a tandem rolling mill which performs cold rolling, when the shape of the analyzed frequency wave form is determined to be a predetermined triangle shape whose frequency component which becomes a peak value of frequency intensity is a vertex, it is detected as the chattering vibrations generated caused by the rolling state (slip, stick). <P>COPYRIGHT: (C)2013,JPO&INPIT |
