The invention belongs to the technical field of aircraft structure design, and particularly relates to a honeycomb plate insert capable of reducing vibration and noise, which comprises a honeycomb plate with a through hole and an insert mounted in the through hole, the insert comprises an elastic body, a metal outer sleeve ring and a metal inner sleeve ring; the elastic body comprises a central cylinder with a central hole and two mounting edges formed by extending the two ends of the central cylinder in the radial direction, each mounting edge is provided with a metal outer lantern ring, and the metal inner lantern ring is arranged in the central hole of the elastic body in a sleeved mode. And moreover, the rigidity of the metal outer sleeve ring and the metal inner sleeve ring can be increased, so that the assembly cost is reduced while the vibration and noise reduction effects are achieved.
本申请属于飞机结构设计技术领域,特别涉及一种可以减振降噪的蜂窝板嵌件,具有穿孔的蜂窝板与安装在所述穿孔中的嵌件;嵌件包括:弹性体、金属外套环和金属内套环;弹性体包括具有中心孔的中心筒体以及中心筒体两端分别径向延伸形成的两个安装边,每个安装边上均安装有金属外套环,金属内套环套在弹性体中心孔中,本申请蜂窝板两端均没有金属直接连接,并且能给通过金属外套环、金属内套环增加刚度,在起到减振降噪作用的同时减少了装配成本。
