Experimental Investigation on Damping Characteristic of Metal Rubber Material at Simulated Marine Environment

Abstract

To meet the need of damping material at the marine corrosive environment, the clamped-edge disk type of metal rubber specimen is designed and its corrosion-load alternate experiment is performed, the anti-corrosive and damping characteristic of the material at the marine corrosive environment is researched. The experimental results show that the corrosive rate of 304 stainless steel metal rubber specimen at cycle-immersion corrosion-load alternate environment is the highest and its decay rate of dynamic average rigidity is also the highest, and followed by full-immersion, cycle-salt-spray and full-salt-spray environment. The damping characteristic of metal rubber specimen is relatively stable at the corrosion-load alternate experiment; the metal rubber material has anti-corrosion ability at marine environment.

Optimization on hysteresis dynamic model of metal rubber material based on dry friction damping term

“…5 Many nonlinear models of this material have been established in theoretical research. The representative models [6][7][8][9][10] include Dunkerly equivalent damping model, double line restoring force model, Bouc-Wen model and Davidenkov model, etc. Among the models, double line restoring model and dunkerly equivalent damping model have the advantages on describing the dry friction characteristics.…”

Research Progress in Preparation Technology of Metal Rubber Blank

“…In the field of military applications, metallic rubber has broad application prospects in the fields of unmanned aerial vehicles, submarine photovoltaic masts, torpedoes, space engines, submarine pipelines, and the like, which need to have both damping and cushioning properties and harsh environments. In the civilian sector, metal rubbers are widely used in fields such as Galileo satellite navigation laser reflectors, meridian sounding rockets, industrial pipelines, deep sea submarines, polar rover robots, etc.that require both cushioning and harsh environments [1][2][3][4].…”
