Design of composite honeycomb vibration isolator for Ships

摘要

Honeycomb porous material has the characteristics of light weight,excellent performance in shock resistance,heat insulation and sound insulation.In this paper,two kinds of hexagonal honeycomb porous materials composite vibration isolators with positive and negative Poisson’s ratio are designed respectively.Through modal analysis and frequency response analysis,the vibration reduction effects of the proposed vibration isolators are demonstrated.Comparative studies on mechanical performance are conducted for the isolators with composite material and steel panels.
