An Archetypal Vibration Isolator with Quasi-zero Stiffness in Multiple Directions [PDF]
Journal of Nonlinear Mathematical Physics, 2022 AbstractTo avoid the failure under the longitudinal, shear, and mixed wave from earthquake, an archetypal vibration isolator based on a smooth and discontinuous (SD) oscillator is proposed. This model comprises a lumped mass mounted by a vertical spring and a horizontal elastic continuum, which separately provides positive and the negative stiffness ...
