Currently, a vibration isolator is used to reduce vibration while preventing vibration generated from an engine, turbine, or machine tool from being transferred to other parts or machines. At this time, as the vibration reduction device, a rubber material-based anti-vibration pad, an elastic vibration mount, or the like, or a vibration mount using a metal spring are commonly used. The rubber material and the spring-based vibration damping device may be selectively used according to the arrangement relationship between parts or required performance, and the following disadvantages occur during use.

Vibration damping devices based on rubber materials have limitations in reducing vibration in the low frequency region due to material characteristics, and have disadvantages in that they depend on experience because it is difficult to accurately grasp the spring constant due to viscoelastic characteristics. In addition, the spring-based vibration damping device can design a spring constant to meet the required conditions, but has a limitation in that the spring constant must be lowered accordingly in order to isolate vibration in a low frequency region. Furthermore, the spring-based vibration damping device may lead to a disadvantage in that, when the spring constant is lowered to isolate low-frequency vibration, the stiffness of the device supporting the device is lowered, and thus the vibration of the device itself increases.

Accordingly, Korean Patent Registration No. 10-2156940 ("Vibration and Noise Reduction Device", published on September 17, 2020) discloses a technology for reducing vibration through a material that absorbs vibration and a structure such as a honeycomb or winding type. A technique for reducing vibration through deformation of is disclosed. However, in the case of using a single material for vibration reduction, there is a problem in that the reduction performance varies depending on the frequency. In addition, in order to reduce vibration in a low frequency region through the currently disclosed structures, since the size of the structures must be designed and manufactured to be fine, there is a problem in that cost and time are excessively consumed. As a result, economic feasibility is low, which may lead to problems that are difficult to apply in practice.
