Nonlinear damping and mass effects of electromagnetic shunt damping for enhanced nonlinear vibration isolation

Hongye Ma et al.

Summary: This study investigates the nonlinear mass and damping effects of nonlinear electromagnetic shunt damping on the vibration isolation performance of a permanent magnets based nonlinear vibration isolator. By designing a specific electromagnetic structure and analyzing the mechanic-electromagnetic coupling coefficient, equivalent nonlinear damping and mass are achieved. The use of inductance is found to change the mass and frequency response of the vibration isolator.

A quasi-zero-stiffness dynamic vibration absorber

Yaopeng Chang et al.

Summary: This paper proposes a quasi-zero-stiffness (QZS) DVA for ultra-low frequency vibration absorption, which is designed using a simple oblique-spring model and verified for its dynamic behavior through the harmonic balance method (HBM) and numerical analyses. Experimental results demonstrate the excellent performance of QZS DVA in absorbing ultra-low frequency vibrations.

A novel lever-type vibration isolator with eddy current damping

Bo Yan et al.

Summary: This study proposes a lever-type vibration isolator with eddy current damping, which can broaden the isolation band by adjusting the lever ratio and improve the vibration suppression performance. The effects of lever ratio, tip mass, material properties, geometric parameters, and excitation amplitude on vibration isolation performance are analyzed. ECD can further enhance vibration suppression in the resonance region, while transmissibility tends to stabilize in the isolation region with increasing lever ratio.

A novel integrated quasi-zero stiffness vibration isolator for coupled translational and rotational vibrations

Kan Ye et al.

Summary: The integrated translational-rotational QZS vibration isolator designed in this paper using the cam-roller mechanism can provide high-static-low-dynamic stiffness in two directions simultaneously, with independent excitations in translational and rotational directions but mutual interaction. The proposed QZS system shows better isolation performance in both translational and rotational directions compared to the linear system without the cam-roller mechanism.

Tunable ultralow frequency wave attenuations in one-dimensional quasi-zero-stiffness metamaterial

Jiaxi Zhou et al.

Summary: This study designed a one-dimensional metamaterial for attenuating ultra-low frequency waves, achieving quasi-zero stiffness through optimized configuration with adjustable band gap structure. Results show that band gap can be tuned by changing pre-compression, enabling attenuation of ultra-low frequency waves.
