| 中文摘要: |
| 目的 研究天然橡胶、丁基橡胶和发泡橡胶等典型工程橡胶的压缩变形行为和缓冲特性。方法 首先总结橡胶材料特性和工程案例，进行三类橡胶的准静态和动态压缩试验，获取材料的应力-应变关系和压缩特性。并以此为基础，给出橡胶缓冲特性表征方法，进而对比和定量分析不同橡胶的缓冲特性。结果 压缩实验结果显示，不同橡胶材料的压缩变形行为基本一致。缓冲特性分析表明，在相同应变水平下，实心橡胶的缓冲吸能能力明显强于发泡橡胶，而在相同应力水平下，橡胶材料的缓冲吸能能力则与材料实际所处受力区域有关。因此，在工程中选取橡胶缓冲材料时，应当考虑其所处的应力环境。结论 根据不同橡胶材料的缓冲规律给出其对应的冲击防护适用场景，以此形成判据，从而为橡胶防护结构材料的选择提供参考。 |

| Objective To study compression and buffering properties of engineering rubber products, including natural rubber, butyl rubber and foamed rubber. Methods On the basis of rubber properties and engineering projects analysis, quasi-static and dynamic compression tests were conducted on the above three kinds of rubber. On this basis, characterization method of buffering properties was give to have comparison and quantitative analysis on buffering properties of various rubber materials. Results The results of compression show that the deformation features of different rubber materials were similar. But the solid rubber obviously performed better in the ability of energy-absorbing compared with the foamed rubber under the same strain level. While, this ability is related to the actual stress region of the material at the same stress level. Consequently, the stress environment of the product should be taken into consideration when choosing the buffer material of rubber in engineering application. Conclusion Applicable scenarios of different rubber’s role as shock shield could be summed up according to their properties, which could be a favorable reference for selection of rubber protective material. |
