Analysis on non-sticking forced vibrations in a dry friction damper system

The paper investigated the steady state of non-sticking motion for a single degree of freedom system that is under harmonic excitation with dry friction,based on the work of Den Hartog and H K Hong,the unnecessary hypotheses are dropped.The expression of maximum velocity of the non-sticking motion is presented,which is the product of the magnification factor B,the natural cycle frequency ω_n and the static displacement of the amplitude of excitation force p_0/k.Numerical simulations validate the theoretical results of maximum velocity.Some discussions about the magnification factor are presented.The phase lags of maximum displacement and velocity are also discussed.
