| 中文摘要: |
| 提出电动汽车轮胎滚动阻力与噪声协调设计理论：选择窄胎面、大外径的轮胎尺寸，将标准充气压力提高到320 kPa，带束层采用大角度设计方案（60°～70°），花纹设计和节距排列在考虑降低滚动阻力的同时兼顾降低噪声。以国内一款B级纯电动汽车为例，为其开发一款电动汽车专用155/65R17轮胎，并进行有限元建模仿真和节距噪声优化，进行滚动阻力计算和六分力预报。结果表明，开发的155/65R17电动汽车轮胎滚动阻力系数为6.36 kg·t-1，达到了A级指标，噪声和操纵稳定性满足设计要求，实现了滚动阻力、噪声和操纵稳定性的协调控制。 |

| The balanced design principles of rolling resistance and noise of electric car tires were presented in this paper.For example，narrow tread and large diameter were preferred，standard tire pressure was increased to high level such as 320 kPa，large angle（60°～70°）was designed for belts，and pattern design and pitch arrangement were aimed at not only low rolling resistance but also low noise.In this study，a domestic B-class electric vehicle was taken as an example，special 155/65R17 electric car tire was developed，finite element modeling and pitch noise optimization were carried out，rolling resistance was calculated，and six component wheel force was predicted.The results showed that，the rolling resistance coefficient was 6.36 kg·t-1，which reached grade A，tire noise and control stability met requirements of the design，and the balanced control of rolling resistance，tire noise and control stability was achieved. |
