摘要

以重载大扁平比（扁平比为1）轮胎为研究对象，基于连续弹性基础的柔性胎体模型为基础，考虑柔性胎体与连续胎侧的耦合振动，建立基于连续弹性基础的柔性胎体轮胎动力学模型；建立了考虑弦预紧效应和结构弯曲特性的胎侧分段解析刚度模型；分析了胎侧曲梁几何和结构参数对胎侧分段刚度、轮胎传递特性及模态频率的影响规律。结果表明：（1）大扁平比胎侧曲梁的径向分段刚度与胎侧曲梁的几何、结构和充气压力参数直接相关；（2）基于胎侧曲梁分段解析刚度模型可实现对轮胎模态频率及传递特性优化设计。

Abstract

The study investigates the kinematic characteristic of the radial tire with a large section ratio (the section ratio is 1) with the continuous analytical elastic foundation modeling. A proposed tire model with a flexible belt on an elastic continuous stiffness foundation considering the coupled feature between the tire carcass and tire sidewall is investigated. The analytical multi-stiffness function of tire sidewall with a large flat ratio is researched with the pre-tension string and structural stiffness resulting from the sidewall deform. The influence on the radial stiffness, transfer function and modal frequency is discussed. The experimental and theoretical results indicate the following: (1) the radial segmented stiffness function of the curved sidewall is related to the inflation pressure, structural curvature, and material properties; (2) the analytical segmented sidewall model can be used to optimize the modal and transfer function of the tire.
