| 中文摘要: |
| 研究4种炭黑（N330，N550，N774，N762）在汽车发动机悬置中的应用。结果表明：不同炭黑对悬置的动静刚度、耐疲劳性能和耐蠕变性能均具有较大的影响；炭黑N330的粒径小、结构度高、比表面积大，其填充胶料的硬度、拉伸强度、弹性模量、动静刚度、疲劳后刚度损失和蠕变量均高于其他3种炭黑填充胶料；悬置橡胶应采用结构度低、粒径大、比表面积小的炭黑，以减小悬置的动静刚度比、蠕变量及疲劳后刚度损失，特别适用于低硬度天然橡胶胶料，炭黑用量不大，有利于低刚度悬置的配方设计。 |

| The application of four kinds of carbon black（N330，N550，N774，N762） in automobile engine mount was studied.The results showed that different carbon blacks had great effects on the dynamic and static stiffness，fatigue resistance and creep resistance of the mount.Due to small particle size，high structure and large specific surface area of carbon black N330，the hardness，tensile strength，elastic modulus，dynamic and static stiffness，stiffness loss after fatigue and creep of carbon black N330 filled compound were higher than those of the other three kinds of carbon black filled compounds.The mount compound should adopt carbon black with low structure，large particle size and small specific surface area to reduce the dynamic and static stiffness ratio，creep and stiffness loss after fatigue.It was especially suitable for natural rubber compound with low hardness，and the amount of carbon black was small，which was conducive to the formulation design of low stiffness mount. |
