轿车轮胎接地印痕有限元优化分析

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。

Finite Element Optimization Analysis on Passenger Car Tire Footprint

Taking 60 series passenger car tire with different section width as study object,the influence of tire contour design parameters including R₁ (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 element 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 mm.This study could provide a reference for the optimization of passenger car tire footprints.
