摘要

发动机隔振器用橡胶材料的关键性能为动态模量和阻尼性能。应变幅值、重复循环和温度的影响是评估隔振橡胶材料的重要判别标准。这类材料包括天然橡胶(NR)、丁基橡胶(BR)、环氧化天然橡胶(ENR)、氯丁橡胶(CR)、三元乙丙(EPDM)/尼龙6共混物、丁腈橡胶(NBR)/(聚甲基丙烯酸甲酯)PMMA共混物等。介绍了上述橡胶材料、橡胶基复合材料及其隔振、抗振性能。这些性能包括阻尼系数、能量损耗、阻尼常数和振动传递比率之间的关联性。
        The key properties of the engine isolate mount rubbers are dynamic modulus and damping. The strain amplitude,repeated cycling and the effect of temperature on these properties are also important parameters to evaluate the vibration- isolating rubber materials,including natural rubber( NR),polybutadiene rubber( BR),epoxidized natural rubber( ENR),Neoprene( CR),ethylene- propylene- diene monomer( EPDM) / nylon 6 blend systems,Nitrile Rubber( NBR) / Poly( Methyl Methacrylate)( PMMA) blend systems,and so on. All above rubber materials and corresponding composite materials as well as their vibration- isolating / antivibration properties,including the correlations between damping factor,energy loss,damping constant,and vibration transmissibility ratio,were introduced.
