Influence of Coulomb damping on vibration absorber

The influence of Coulomb damping on vibration absorber. The model of Coulomb damping was introduced concerning Coulomb damping in the vibration absorber, two relative motions between the master vibration system and the addition mass, sticking and sliding, were analyzed, and the conditions in which two motions and alternate were discussed, as well as the freezing of the degree of freedom due to coulomb damping. Numerical simulation was conducted using Simulink of MATLAB to study the vibration absorbing excited by harmonic and white noise and the equivalence between coulomb damping and linear damping.
