| 中文摘要: |
| 通过试验对比聚酯型聚氨酯海绵和聚醚型聚氨酯海绵的吸声系数，研究海绵轮胎和普通轮胎的力传递率曲线差异以及对车内噪声的影响。结果表明：聚酯型聚氨酯海绵的吸声系数大于聚醚型聚氨酯海绵；不同材质的海绵对轮胎力传递率曲线影响不明显，但降噪效果差异明显，聚酯型聚氨酯海绵比聚醚型聚氨酯海绵的降噪效果好；对于同种海绵，低速度下的降噪效果较好，随着速度的增大，降噪效果大致呈减弱趋势。 |
| 英文摘要: |
| By comparing the sound absorption coefficients of polyester polyurethane sponge and polyether polyurethane sponge through experiments，the difference in force transfer rate curves between sponge tires and regular tires，as well as the impact on vehicle interior noise，were studied.The results showed that the sound absorption coefficient of polyester polyurethane sponge was greater than that of polyether polyurethane sponge.The influence of sponges made of different materials on the tire force transfer rate curve was not significant，but the noise reduction effect varied significantly，the polyester polyurethane sponges had better noise reduction effect than polyether polyurethane sponges.For the same type of sponge，the noise reduction effect was better at low speeds，and as the speed increasing，the noise reduction effect roughly showed a weakening trend. |
