Since the damping force of electromagnetic shunt (EMSD) devices can be adjusted by controlling external circuit, in order to further enhance its vibration reduction performance resonance region isolation system, a displacement-dependent (D-EMSD) system is developed incorporating sliding rheostat. Utilizing approximate analytical solution solved via harmonic balance method, dynamic quasi-zero-stiffness (QZS) isolator integrated with D-EMSD are examined. Concurrently, stability conditions for steady periodic solutions deduced employing Lyapunov first method and Routh-Hurwitz criterion. A comprehensive analysis conducted on influence various parameters amplitude-frequency response transmission characteristics primary QZS system. The results show that simultaneously decrease peak values amplitude transfer rate within main zone, which improves capability zone without compromising high-frequency capability.
