| 中文摘要: |
| 利用轮胎有限元模型，探讨电动汽车轮胎低温滚动阻力性能的影响因素及相关优化措施。结果表明：环境温度降低，胎面胶和基部胶的低温滚动阻力增长率较高，优化胎面胶的玻璃化转变温度可以在降低轮胎低温滚动阻力的同时保持良好的抓着性能；在结构设计方面，适度增大基部胶厚度、减小带束层角度以及采用1层或加强型1层胎体结构，有助于降低轮胎的低温滚动阻力。 |
| 英文摘要: |
| Using the finite element model of the tire，the influencing factors and related optimization measures of low-temperature rolling resistance performance of electric vehicle tires were explored.The results showed that the ambient temperature decreased，the growth rates of low-temperature rolling resistance of the tread compound and base compound were higher.Optimizing the glass transition temperature of the tread compound could reduce the low-temperature rolling resistance of the tire while maintaining good grip performance.In terms of structure design，moderately increasing the thickness of the base compound，reducing the angle of the belt，and adopting a 1-layer or reinforced 1-layer carcass structure could help reduce the low-temperature rolling resistance of the tire. |
