摘要
采用单一变量法及正交试验法,研究结构参数对电动汽车轮胎性能的影响.结果表明:无论采用单一变量法还是正交试验法,电动汽车轮胎静态特性中的刚度变化趋势与操纵稳定性中的刚度变化趋势相同;但当改变胎体帘线经线密度和三角胶高度时,电动汽车轮胎的侧偏刚度和纵滑刚度的变化趋势不同.在指定的分析条件下,带束层角度、带束层宽度及冠带条铺贴方式对电动汽车轮胎接地特性影响较大;带束层角度及三角胶高度对轮胎滚动阻力和静态刚度影响较大;带束层角度及带束层帘线经线密度对轮胎操纵稳定性影响较大.
Abstract
The influence of structural parameters on the performance of electric vehicle tires was studied using the single variable method and the orthogonal experimental method.The results showed that,regardless of using the single variable method or orthogonal experimental method,the stiffness variation trend in the static characteristics of electric vehicle tires was the same as that in the handling stability.However,when changing the carcass cord longitudinal density and the apex height,the variation trends of the lateral stiffness and longitudinal slip stiffness of electric vehicle tires were different.Under the specified analysis conditions,the angle and width of the belt,as well as the method of laying the crown strip,had a greater impact on the grounding characteristics of electric vehicle tires.The belt angle and the apex height had a greater impact on the rolling resistance and the static stiffness of the tire.The belt angle and the belt cord longitudinal density had a greater impact on tire handling stability.
