摘要
分析成型工艺中影响半钢子午线轮胎均匀性的因素,考察冠带条缠绕张力和胎面接头量对轮胎均匀性的影响,介绍胎坯均匀性分析系统的应用。结果表明:随着轮胎扁平率增大,冠带条缠绕张力增大,轮胎高速性能下降,但均匀性变化规律不明显,应根据轮胎扁平率控制冠带条缠绕张力;胎面接头量过大和过小时,轮胎径向力波动的最大振幅发生位置集中于胎面接头处,影响轮胎的均匀性。采用胎坯均匀性分析系统可以改进胎坯的外观形状,提高产品性能。
In this paper,the green tire uniformity analysis system was introduced and the factors infl uencing the uniformity of semi-steel radial tire were analyzed. Main factors were winding tension and rubber volume at tread joint. It was found that when the tire fl at rate increased,the winding tension of crown belt increased,the high-tread joint. It was found that when the tire speed performance of the tire decreased,but the variation of tire uniformity was not clear. The winding tension should be adjusted based on tire flat rate. When the joint volume was too much or not enough,the maximum amplitude of the radial force variation of the tire centered on the joint position,which affected the tire uniformity. amplitude of the radial force variation of the tire centered on the joint position,which affected the tire uniformity. It was demonstrated that with green tire uniformity analysis system,the green tire shape could be optimized in advance and the product quality was improved.advance and the product quality was improved.
