轮胎施工参数对横向刚性的影响

Influence of Tire Construction Parameters on Lateral Rigidity

以205/55R1691V轮胎为例,采用正交试验设计方法研究带束层角度、带束层宽度、带束层单根钢丝帘线强力和锦纶冠带层缠绕方式对轮胎横向刚性的影响。结果表明:较优施工设计方案为带束层角度26°,带束层宽度170 mm,带束层单根钢丝帘线强力700 N,冠带层缠绕方式单层;4个因素对轮胎横向刚性的影响由大到小的顺序为带束层单根钢丝帘线强力、带束层宽度、带束层角度、锦纶冠带层缠绕方式。方差分析表明4个因素两两之间均存在交互作用。

Taking the 205/55R1691V tire as an example,the effects of belt angle,belt width,strength of a single steel cord for belt and nylon crown belt winding method on tire lateral rigidity were studied by orthogonal experimental design method.The results showed that the optimal construction design scheme was the belt angle of 26°,the belt width of 170 mm,the strength of a single steel cord for belt of 700 N,and the single layer winding method of the crown belt layer.The order of influence of four factors on tire lateral rigidity from large to small was strength of a single steel cord for belt,belt width,belt angle,and nylon crown belt winding method.The analysis of variance on the test results showed that there was interaction between the four factors.
