Composite vibration control body and metal spring equipped composite vibration control body using same

Abstract

Provided are a composite vibration control body with a novel structure and a metal spring equipped composite vibration control body using the composite vibration control body with a novel structure, with which superior vibration control properties can be realized. A composite vibration control body 10 has a structure in which a first elastic body 12 and a second elastic body 14 are mutually overlapped, wherein: the first elastic body 12 is formed from a material with greater attenuation than the second elastic body 14; a recessed section 18 that opens to a surface of the first elastic body 12is provided so that a space 22 is formed by the recessed section 18; and a strain section 28, where strain is greater when a load is applied, is provided in a wall section of the space 22 in the elastic body 12.

Description

technical field [0001] The present invention relates to a composite vibration isolator used when, for example, maintaining components of a vibration transmission system in a vibration-proof connection state or restricting relative displacement of components of a vibration transmission system, and a metal spring using the composite vibration isolator Composite anti-vibration body. Background technique [0002] Conventionally, for example, as an anti-vibration body suitable for use in a door stopper for positioning a door of a vehicle relative to a vehicle body frame, and a stopper mechanism of an anti-vibration device such as an engine mount, a plurality of elastic bodies have been proposed. Composite anti-vibration body with overlapping structure. That is, the composite anti-vibration body has a structure in which an outer body and an inner body formed of a rubber elastic body overlap each other, as in the stopper shown in Japanese Patent Laid-Open No. 2016-125528 (Patent D...

AI Technical Summary

Problems solved by technology

[0004] However, in the stopper of Patent Document 1, when the load is input, the overall deformation of the outer body and the inner body causes the strain to be dispersed, so the damping effect is relatively small and the vibration-proof performance may be insufficient.
