| 中文摘要: |
| 综合利用试验和有限元仿真方法，并引入不对称因子表征轮胎接地印痕的不对称性，研究结构偏差（带束层整体偏移和左右胎肩厚度差异）对轮胎接地印痕的影响。结果表明，结构偏差易造成轮胎接地印痕不对称，其中左右胎肩厚度差异比带束层整体偏移对轮胎接地印痕不对称性的影响更为显著。本研究结果为轮胎生产工艺控制和改善轮胎接地印痕提供了依据。 |
| 英文摘要: |
| Comprehensive use of experiments and finite element simulation methods，and introduced an asymmetry factor to characterize the asymmetry of the tire footprint，the influence of tire structural deviation （the overall belt drift and the left and right shoulder thickness difference） on the tire footprint was studied.The results showed that the structural deviation was likely to cause the asymmetry of the tire footprint.The left and right shoulder thickness difference had a more significant influence on the asymmetry of the tire footprint than the overall belt drift.The results of this study provided a basis for the tire production process control and improvement of the tire footprint. |
