胎面轮廓形状优化技术研究--提高轮胎耐磨耗性能

胎面轮廓形状对轮胎的耐磨耗性能影响很大，因此对其进行优化很有意义。针对胎面轮廓形状比较复杂的特点，文中采用多个变量来定义胎面轮廓。同时，在现有磨耗理论的基础上，通过对胎面轮廓形状的优化初步给出了评价轮胎耐磨耗性能的指标。在此基础上，采用自编的多目标优化程序对胎面轮廓进行优化，并将计算结果与原胎数据进行了比较，结果表明，不论是从胎面的磨耗速度还是从胎面磨耗的均匀性来说优化胎都要优于原始。

Improve the Wear Resistance Performance of Vehicle Wheel Tyre--Research on Optimization Technology for Tread Profile

Optimizing the tyre tread profile is very significant because the tread profile has a big effect on wear resistance performance of vehicle wheel tyre. In view of the characteristics of complicated tread profiles, defining the tread profiles by multi - variables are described in this paper and on the basis of present wear theories, the indexes for evaluating wear resistance performances.of tyres are given preliminarily at the same time through optimizing the tread profile. On this base, the tread profiles are optimized by self - made multi - target optimization programs, and the calculation results are compared with those of original tyres. The results indicate that the optimized tyres are superior to those original tyres for both wear speed and wear uniformity of tread.
