Abstract:

The strengh properties of damping rubber had connections with vibration property of rubber vibration isolator. Through the analysis of the cure of tensile strengh ,it looked for the effect of tensile strength at 200% on dynamic property of damping rubber. It has been found that tensile strength at 200% of rubber was larger, which would make Kd/Ks of damping rubber. Addionally,through the analysis of the cure of, the rerult showed that the angle of σ-ε cure with ε axe,the Kd/Ks of the rubber was small. The effect of rubber and CB and sulfur amount on mechanical properties and Kd/Ks were also studied. It was shown that Kd/Ks decreased and tensile strength increased as the particle size of CB increased. So reinforcing agent with middle particle size or different particle size (bigger and smaller) added together could meet the requirements of strength and vibration effect at the meantime. Additionally, increasing the amount of sulfur properly could make 200% TS improving and vibration effect better.
