Comments on “finite element model for dynamic analysis of Timoshenko beam”

An analysis is presented of the effect of dry friction on vibrations of two self-excited systems. Attention is directed to cases where practical quenching of self-excited vibrations cannot be achieved merely by the action of linear additional damping. It is shown that at correct tuning of the systems discussed, a combination of linear additional damping with dry friction is so effective in limiting their amplitudes that self-excited vibrations may be regarded as practically suppressed.
