Czech term or phrase: pružná vazba
Na stožáru televizního vysílače v západních Čechách byly v roce 1979 pozorovány torzní kmity, které nakonec vedly k jeho havárii. Naskytla se v té souvislosti otázka, zda je možná *** pružná vazba *** mezi ohybovými a torzními kmity, která by mohla vyvolat aeroelastické nestabilní kmitání typu flutter, a protože dřík je tuhostně souměrný, zbývá možnost vazby přes lanové podpory. Ukazuje se, že tato vazba možná je, jinak řečeno, že při posunu podpory může kromě síly bránící posunu vzniknout i moment, který má snahu stožár kroutit nebo v případě kloubového uložení dříku, pootočit.


Děkuji za nápady.

English translation:elastic coupling
Explanation:
Z jedné knihy:

For composite beams, this choice of x-axis uncouples torsion and transverse shear deformation, but torsion and transverse displacements may remain coupled depending on whether the beam has bending-torsion elastic coupling. For a further simplification, we assume that cross-sectional mass centroids lie along the elastic axis, in which case transverse motions due to bending are inertially uncoupled from torsional motion.
