轮胎花纹性能的优化设计

摘要

For tire tread design, we select tire grip and intensity of noise for evaluation. For grip: by stress analysis of tire driving, we use physical knowledge derived approximate formula for calculating grip tires. In addition, we substitute data for verification. According to the verified results, we design a good grip performance tire tread. For tire noise: in line with the waveform pattern grooves, we tread grooves sound system dynamics analysis, considering interference with the synthesis of the tire, we obtain the equation tire noise. Theoretical analysis, we design a weak tire tread noise. Based on the above last two aspects, we depend on the design of the tire corresponding to the specific circumstances.%对于轮胎的花纹设计，选取轮胎的抓地力和降噪音作为评价指标。对抓地力：对轮胎行驶过程中受力分析，借助物理知识得出轮胎的抓地力的近似计算公式，代入数据进行验证，根据验证结果，设计出抓地性能好的轮胎花纹。对轮胎噪音：根据花纹槽的波形，对花纹槽的发声系统进行动力学分析，综合考虑轮胎的干涉与合成，得出轮胎噪音的公式表示，结合理论分析，设计出轮胎噪音很弱的轮胎花纹。最后综合以上两个方面，根据不同的具体情况设计对应的轮胎。
