Abstract

A flexible carcass ring model with a two-dimensional elastic foundation that combined a flexible carcass ring and a two-dimensional spring element was used to analyze the contact boundary of heavy load radial tyres with a large section ratio. A complete tyre model based on the flexible ring was established and the contact features were studied by solving the theoretical boundary for its contact and non-contact zones. The contact stiffness and imprint were validated in rolling and stiffness experiments. The scope for contact estimation was examined by using an in-tyre strain sensor and the influence of the axle load, inflation pressure and rolling speed on the asymmetry of the contact imprint was analyzed. The experimental and theoretical results show that the contact front/rear angle and contact imprint can be estimated exactly by computing the contact boundary. In-tyre strain signals can be further used to estimate the length of the contact imprint. This research can be used to enrich existing simplified physical tyre models.

重载子午线轮胎滚动接触不对称性分析

采用柔性胎体环与二维弹簧单元相结合的二维弹性基础柔性胎体环模型，分析了大断面比重载子午线轮胎的接触边界。建立了基于柔性环的完整轮胎模型，通过求解其接触区和非接触区理论边界，研究了其接触特征。通过轧制和刚度试验验证了接触刚度和压痕。采用胎内应变传感器检测了接触估计的范围，分析了轴重、充气压力和滚动速度对接触压痕不对称性的影响。实验和理论结果表明，通过计算接触边界可以准确估计接触前后角和接触压痕。轮胎内应变信号可以进一步用来估计接触压印的长度。该研究可用于丰富现有的简化轮胎物理模型。
