摘要以某空调器压缩机橡胶隔振脚垫为研究对象，考虑热氧老化对橡胶隔振脚垫的动态特性影响，采用Arrhenius模型、分数导数Kelvin-Voigt模型和库仑摩擦模型对橡胶隔振脚垫进行动态特性建模，建立了橡胶隔振脚垫热氧老化-动态特性数学模型。基于MTS831弹性体试验台搭建了隔振脚垫静、动态特性测试装置，给出了模型参数的辨识方法，实验验证了热氧老化-动态特性数学模型的正确性。结果表明，在100℃热氧老化7天后，橡胶隔振脚垫静刚度增长19.35%，动刚度最大增长5.3%，损耗因子最大减小11.6%。热氧老化-动态特性模型能够有效地表征橡胶隔振脚垫动态特性的振幅相关性、频率相关性和热氧老化相关性，为深入研究计及外界环境温度因素导致橡胶热氧老化的隔振脚垫服役后动态特性演化规律提供基础。

Abstract：Taking a rubber isolation pad of air conditioning compressor as the research object and considering the effect of thermal oxygen aging on its dynamic characteristics, a mathematical model of thermal oxygen aging-dynamic characteristics of rubber isolation pad is established by adopting the Arrhenius model, the fractional derivative Kelvin-Voigt model and smooth Coulomb friction model. Based on the MTS831 elastomer test bench, a test rig for static and dynamic characteristics of rubber isolation pads is built, and a method for identifying model parameters is proposed. The experimental results verify the correctness of the mathematical model of thermal oxygen aging-dynamic characteristics. It is shown that the static stiffness of rubber isolation pads increases by 19.35%, the maximum dynamic stiffness increases by 5.3% and the maximum loss factor decreases by 11.6% after thermal oxygen aging 7 days. Moreover, the thermal oxygen aging-dynamic characteristics model can effectively characterize the amplitude-dependent, frequency-dependent and thermal oxygen aging-dependent performances of rubber isolation pads. This paper can provide a basis for further research on evolution law of dynamic characteristics of rubber isolation pads after its service with thermal oxygen aging caused by ambient temperature.
