Re: CQC and SRSS

[Subject Prev][Subject Next][Thread Prev][Thread Next]
Dear colleagues,

With full respect to all who correctly pointed out some useful comments,
you may have a look at the followin papers for further details, of course
there are many other else. Just keep in mind that the CQC appears much
superior when the torsional modes are among the dominated modes, i.e. 1st
3-5 modes. This may be caused by closedly-spaced modes and/or specific plan
