This invention relates to an aperiodic layered vibration isolator and its design method. The aperiodic layered vibration isolator comprises N or more sets of aperiodic unit structures connected in series, each set of aperiodic unit structures including a rubber layer and a metal layer. The design method of the aperiodic layered vibration isolator includes the following steps: determining the dynamic element stiffness matrix of each metal layer and rubber layer to obtain the unit transfer matrix of the vibration isolator; determining that the total transfer matrix of the aperiodic layered vibration isolator is the product of the transfer matrices of N elements, and obtaining its wave propagation characteristics through eigenvalue analysis of the transfer matrix of the vibration isolator; adjusting the thickness HM of each metal layer of the aperiodic layered vibration isolator. i and rubber layer thickness HR i The design parameters selected cover a wide range of wave-blocking frequencies. This invention improves upon existing periodic vibration isolators, broadening their wave-blocking frequency range. The layered structure also features simple design and compact space.
