The stiffness characteristic of a nonlinear vibration isolator is studied. Based on buckling theory, the force-displacement and stiffness-displacement relationships of an oblique thin-walled beam are analyzed, and the existence of negative stiffness is discussed. A prototype of the nonlinear vibration isolator is proposed. Its high-static and low-dynamic (HSLD) stiffness characteristics are validated by mutual comparison of the theoretical and experimental results.
