Numerical simulations of the nonlinear vibrations of the system are carried out for different values of the MRD control parameter in order to show the amplitude reduction of the vibrations close to the system resonance introduced by the nonlinear damping effect of the MR system.1112-1118engMR dampernon-ideal systemSommerfeld EffectArtigo10.1177/1077546310384000WOS:000291007600015Acesso restrito
