摘要
Introduction To improve the low frequency isolation capability of vibration isolation system, a kind of electromagnetic quasi-zero-stiffness (QZS) vibration isolator was designed. Materials and methods The negative stiffness electromagnetic spring paralleled with the linear positive stiffness spring to achieve the state of QZS. The nonlinear dynamic model of vibration isolator was established. Through the combination of theoretical formula and simulation analysis, the electromagnetic force expression was obtained. The amplitude-frequency responsecharacteristics and force transmissibility was solved by harmonic balance method, and the effects of system parameters on amplitude - frequency characteristics and transmissibility was analyzed. Conclusion The results show that the new isolator has better performance than the linear system, and the decreased damping ratio and excitation amplitude make the effects of vibration isolation of system superior.
