Nonlinear antiresonance vibrating screen

A mathematical model of two masses vibrating screen with nonlinear elastic and dissipative ties working under ideal harmonic excitation is considered. The focus of the work is the study of the stationary movements in the “antiresonance” zone between the two natural frequencies. Using harmonic balance method the construction and analysis of bifurcation diagrams of this dynamical system are carried out. The spectral and phase composition of the 2:1 superharmonic regimes is demonstrated, technological parameters of such machines are evaluated.
