新型子午斜交轮胎结构设计与力学性能研究

Structure Design and Mechanical Properties of New Radial-Bias Tire

提出一种新型子午斜交轮胎胎体结构,利用有限元软件Abaqus建立三维有限元模型,并对其接地性能和骨架材料力学性能进行分析。研究结果表明,子午斜交轮胎结构通过提高胎侧径向刚性和控制胎肩变形,减小了胎肩的应力集中,改善了轮胎接地压力分布均匀性,避免了轮胎断面轮廓畸变,有利于提高轮胎的承载性能、耐磨性能和操控性能。

A new structure of radial-bias tire carcass was discussed in this paper.A three-dimensional finite element model of the radial-bias tire was established using Abaqus and the grounding performance of the tire and mechanical properties of the reinforcement materials were analyzed. The results showed that,by improving the radial stiffness of sidewall and controlling deformation of shoulder,the shoulder stress concentration of radial-bias tire could be reduced,the uniformity of tire ground pressure distribution was improved,and the distortion of tire cross-section profile could be avoided,which could enhance tire load capacity,wear resistance and steering performance.
