| 中文摘要: |
| 研究温度对纯胶发动机悬置和液封发动机悬置性能的影响、生胶和软化剂对硫化胶耐低温性能的影响以及耐低温改进配方胶料发动机悬置刚度变化。结果表明：随着温度的降低，纯胶发动机悬置和液封发动机悬置的刚度增大，液封发动机悬置阻尼特性频率段阻尼角减小；采用天然橡胶/顺丁橡胶并用胶、低倾点软化剂可改善硫化胶低温性能，提高发动机悬置的耐低温稳定性。 |
| 英文摘要: |
| The effect of temperature on the performance of pure rubber engine mount and hydraulic engine mount was studied，the influence of raw rubber and softener on the low-temperature resistance of the vulcanizates was investigated，and the stiffness change of rubber engine mount using the modified compound with good low-temperature performance was discussed. The results showed that with the decrease of temperature，the stiffness of the pure rubber engine mount and hydraulic engine mount increased，and the damping angle of the hydraulic engine mount in the damping frequency range was reduced. This study showed that by using the blend of natural rubber/butadiene rubber as the main rubber material and the softener with low pour point，the low temperature performance of the vulcanizate and the low temperature stability of the engine mount were improved. |
