ABSTRACT

With the development of high-end equipment towards higher precision, stability and integration, environmental vibration has become a significant factor restricting system performance. Traditional linear vibration isolators rely on fixed stiffness and damping parameters, and their vibration isolation effect is limited by the natural frequency: to achieve a lower vibration isolation starting frequency, the support stiffness must be reduced, but this leads to increased static deflection, decreased load-bearing capacity and deteriorated attitude stability, thus forming a typical "low-frequency vibration isolation - static load-bearing" contradiction. In recent years, nonlinear vibration isolation technology has provided a new path to break through the performance boundaries of linear vibration isolation by introducing geometric nonlinearity, magnetoelastic coupling, buckling flip structures and nonlinear energy transfer mechanisms; among them, the QZS vibration isolator can maintain a high static stiffness and load-bearing capacity while making the equivalent dynamic stiffness near the equilibrium point approach zero, significantly reducing the system's natural frequency and improving low-frequency vibration isolation performance. At the same time, bionic vibration isolators, by imitating the hierarchical compliance and multi-path energy dissipation characteristics of biological structures, have shown unique advantages in lightweight, robustness and working condition adaptability.
