| 中文摘要: |
| 基于田口设计方法，选取对轮胎空腔噪声可能产生影响的5个结构因子（模具、带束层角度、三角胶高度、胎侧厚度和胎面厚度），每个因子取两种水平并设计方案。通过半消声室转鼓噪声试验模拟测试在速度为100～40 km·h-1的匀减速工况下，频率为200～250 Hz的空腔噪声，并根据田口理论分析结构因子对空腔噪声的影响主次顺序、显著程度、各个因子水平变化引起的空腔噪声变化趋势。结果表明：在70～60 km·h-1的减速区间内，带束层角度对空腔噪声的改善有显著的影响；在90～70 km·h-1的减速区间内，带束层角度和胎侧厚度对空腔噪声的改善有显著的影响；在100～90 km·h-1的减速区间内，模具、三角胶高度、胎面厚度和胎侧厚度对空腔噪声影响显著；综合分析得到的最优方案为：带束层角度 24°，胎侧厚度 6.2/7.0 mm，三角胶高度 15 mm，模具 2#，胎面厚度 6.5/8.5 mm。 |
| 英文摘要: |
| Based on Taguchi design method，five structural factors that may affect the tire cavity noise were selected（mold，belt angle，apex height，sidewall compound thickness and tread compound thickness），and took two levels for each factor and designed the scheme．Through the drum noise test of semi anechoic chamber，the cavity noise with frequency of 200～250 Hz under the uniform deceleration condition with speed of 100～40 km·h-1 was simulated and tested．According to Taguchi theory，the influence order and significance of structural factors，and the change trend of cavity noise caused by the change of each factor level were analyzed．The results showed that the belt angle had a significant effect on the improvement of cavity noise in the deceleration speed range of 70～60 km·h-1.In the deceleration speed range of 90～70 km ·h-1，the belt angle and sidewall compound thickness had a significant impact on the improvement of cavity noise.In the deceleration speed range of 100～90 km·h-1，the cavity noise was significantly affected by the mold，apex height，tread compound thickness and sidewall compound thickness.The optimal scheme obtained by comprehensive analysis was：belt angle 24°，sidewall compound thickness 6.2/7.0 mm，apex height 15 mm，mold 2#，tread compound thickness 6.5/8.5 mm. |
