Embodiment Construction

[0026] Below in conjunction with accompanying drawing and specific embodiment, the technical solution of the present invention is described in detail:

[0027] figure 1 The common Moebius ribbon structure shown is a Moebius ribbon structure with initially curved and twisted one-sided surfaces.

[0028] figure 2 It is a schematic diagram of a parallel structure composed of the above-mentioned Moebius strip structure, which is composed of an upper load-bearing platform 1, two Moebius belt structures 2 and a lower load-bearing platform 3. The upper load-bearing platform 1 is a mass block with two wedge-shaped curved surfaces at the bottom. The upper load-bearing platform 1 and the lower load-bearing platform 3 are respectively connected to the upper slope area and the lower arc area of ​​the Moebius belt structure 2 by bolts, so as to link the two Moebius belt structures 2 together. The damping effect of the structure can be enhanced by pasting a free damping layer with a thi...

Abstract

The invention relates to a Moebius vibration isolator based on a wave mode conversion mechanism and an energy local effect. The Moebius vibration isolator is formed by combining multiple Moebius banded structures, and the multiple Moebius banded structures are connected into an integral structure through an upper part bearing force platform and a lower part bearing force platform; and the upper part bearing force platform and the lower part bearing force platform are respectively connected with upper part inclined plane regions and lower part circular arc regions of the Moebius banded structures. The Moebius vibration isolator provided by the invention couples the bending rigidity and torsional rigidity of the Moebius banded structures, the energy local region property is taken as an vibration isolation structure of a vibration isolation mechanism, and the Moebius vibration isolator has the advantages of large load-carrying ability, small static transformation, low inherent frequency, higher damping, and is capable of realizing low-frequency broad band transfer admittance and can not generate creepage, aging and temperature sensibility and the like.

Description

technical field [0001] The invention relates to a vibration isolator, more specifically, relates to a vibration isolator using the wave mode conversion mechanism and energy localization effect of the Moebius strip structure as the vibration isolation mechanism. Background technique [0002] Vibration isolators are widely used in vibration isolation of mechanical equipment. The design goal of using a vibration isolator is to make the natural frequency of the vibration isolation system as low as possible and the vibration isolation efficiency as high as possible. However, the static stiffness that determines its bearing capacity and stability and the dynamic stiffness that determine its vibration isolation performance are a pair of contradictions. From the perspective of vibration isolator design, the requirement for static stiffness is to make the vibration isolator have a large bearing capacity and small deformation in all directions to meet the stability requirements; the ...
