一些作者在发表的文献中提出了轮胎平衡轮廓的好处,研究出了形象描绘斜交轮胎的数学方法。但对于现代子午线轮胎,特别是对那些具有较低断面高宽比的轮胎而言,轮胎的结构则要复杂得多,这就为数学分析提出了新的问题。本文拟提出解决这些问题的方法。对于现代子午线旅游车轮胎来说,平衡轮廓的计算是结合生产这种轮胎的模具轮廓进行的。然后,通过对这些轮胎进行一些结构上的改进来解决这些轮胎轮廓的“不平衡”。利用有限元方法分析了所有适应或不适应平衡轮廓的轮胎内部的应力集中和变形。最后,通过在充气和负载状态下分析轮胎的内部应力和变形进行实际的轮胎试验,证实了拥有平衡轮廓的轮胎具备优异的耐久性,由此可以推断平衡轮廓是现代子午线轮胎的一项有益的特性参数。
Some authors have proposed the benefits of balanced tire contouring in published literature and developed the mathematical approach to characterizing skewed tires. But for modern radial tires, especially for tires with a lower profile aspect ratio, the structure of the tire is much more complex, presenting new problems for mathematical analysis. This article intends to propose ways to solve these problems. For modern radial cart tires, the calculation of the balance profile is made in conjunction with the mold profile used to produce the tire. The “imbalances” of these tire profiles are then solved by making some structural improvements to these tires. The finite element method was used to analyze the stress concentration and deformation of all the tires that fit or did not adapt to the balanced contour. Finally, actual tire testing by analyzing the internal stress and deformation of the tire under inflated and loaded conditions confirms that the tire with a balanced profile has excellent durability, from which it can be inferred that the balanced profile is a benefit of modern radial tires Characteristic parameters.
