The Experimental Analysis And Evaluation Research On Performance Of Metal Rubber Material

The metal rubber material is the elastic component of metal rubber damper. The metalrubber damper can be with strong ability of bearing damping characteristics, good shockresistance, high temperature resistant, also has great environment adaptability, hightemperature resistant, low temperature resistance, corrosion resistance and other properties. Itapplies to harsh environments, such as military power. The performance analysis andevaluation research of metal rubber material have the vital significance to improveperformance and longevity of metal rubber damper.For two kinds of corrosion resistant stainless steel material in this article(the brand for304and321), the diameter of0.3mm and grades of304(CJ) mental wire material has goodcomprehensive performance through comprehensive material composition analysis, SEMsurface morphology, hardness, repeatedly, one-way reverse bend average value, averageroughness of the material, and corrosion resistance, etc.Elastic parts use the diameter of0.3mm and brand for304(CJ) mental wire material. Theresearch on the preparation and performance of metal rubber, select connection weaving asweaving method of the preparation of metal rubber, which has good regularity of repeat unit.And the network density is the key parameter of metal rubber damper. The experimentalresults show that the density of0.90g/cm3metal damper has good Comprehensiveperformance of damping and stiffness.Design AAW–400A metal rubber damper to match the military engine. Do the static testfor describing the characteristics of metal rubber damper, and learned that the metal rubberdamper is non-linear and can effectively control the vibration. The bench test indicates thatmetal rubber damper can reduce the vibration intensity of the whole engine and has a good vibration isolation effect.
