摘要
以60系列不同断面宽的轿车轮胎为研究对象,利用有限元方法研究轮胎外轮廓设计参数胎面第1段弧半径(R1)、第2段弧半径(R2)和胎冠弧度高(h)对轮胎接地印痕的影响。结果表明,R1值取约为断面宽的3倍为佳,R2和h取值越大,轮胎的接地印痕越好,但h的取值最好为8或8.5mm。该研究可为轿车轮胎接地印痕优化提供参考依据。
Taking 60 series passenger car tire with different section width as study object, the influ- ence of tire contour design parameters including R~ （radius of the first arc of tire tread） ,R2 （radius of the second arc） and h （arc height of the tire crown） on the tire footprint was investigated by finite ele- ment analysis method. The results showed that, the bigger the R2 and h values were, the better the tire footprint was. The optimum R1 was approximately 3 times of the section width, and the preferred h value was 8 or 8.5 ram. This study could provide a reference for the optimization of passenger car tire footprints.
