Antivibration and vibration isolation of ENR/CR blends

Abstract

ABSTRACT:The dynamic mechanical properties, hysteresis behavior, antivibration, and vibration isolation of blends of epoxidized natural rubber (ENR) and Neoprene (CR) with various blending ratios, were investigated. The experimental results of ENR/CR blends show that the vibration isolation of ENR is better than that of CR, and the vibration isolation of ENR/CR blends increases with increasing ENR content. Based on the data of vibration transmissibility ratio, ENR has better vibration isolation and the CR has better antivibration. Thus, antivibration and vibration isolation are complemented for the ENR/CR blends.

“…Such correlations are helpful for future design of suitable blends for the purposes of antivibration and vibration isolation. Based on transmissibility ratio results, CR shows better performance in antivibration than ENR [8].…”

“…Moreover, some kinds of electromagnetism mount including active-control mechanism were also designed and provided especially for limousines and business aircraft. Although novel structures, new materials, and creative isolate mechanisms are developed following the developing of the vehicle, the elastomers such as rubber [3][4][5][6][7][8][9][10], plastic composite materials [11][12][13], and rubber/plastic composite materials [14,15] occupy the dominate position of the engine isolate mount areas. The effect of strain amplitude, repeated cycling, and temperature influence on these properties are also important to evaluate the potential engine isolate mount elastomers.…”
