摘要: 在分析现有子午线轮胎非平衡轮廓设计理论的基础上,结合酒井秀男和FRANK非平衡轮廓理论的特点,进行两种理论的融合,得到新的轮胎充气非平衡内轮廓的积分方程,并编制相应的软件。以315/60R22.5及385/55R19.5两种载重子午线轮胎为研究对象,利用提出的轮廓积分方程进行设计。结合轮胎有限元分析技术,从接地压力分布、胎圈和胎肩处的应变比能等方面,对非平衡轮廓设计和现行设计的轮胎进行综合对比分析。结果表明,利用提出的非平衡轮廓积分方程设计的轮胎,接地压力均匀性和接地形状以及胎圈和胎肩处的应变比能具有大幅度地改善,即提高了轮胎的磨损、抓地和疲劳性能。

Abstract: An analysis on the existing radial tire nonequilibrium contour design theory and the characteristics of NORIKO’s and FRANK’s theory is conducted,based on which a combination of NORIKO’s and FRANK’s theory is made. And a new pneumatic tyre nonequilibrium contour integral equation is obtained. Meanwhile a software concerned is successfully developed. A design of the radial tyre 315/60 R22. 5 and 385/55 R19. 5 based on the equation above are put foward. With the finite element technology, a comprehensive contrastive analysis between this very design and the current design is made from aspect of pressure distribution, strain energy potential on the rim and tire shoulders. The results show that, the new designed tyre using the proposed nonequilibrium integral equation,compared with the former,have been substantially improved on the aspect of strain energy potential on tire bead and tire shoulder, namely the tire wear,grip and fatigue performance have been promoted.
