Abstract

Non-pneumatic tires have the advantages of high safety and high load-carrying capacity, and have a broad potential for engineering applications. In this paper, the effects of different gradient angles on the static and dynamic performance of honeycomb spoke structure are studied. First of all, according to different gradient and gradient-free Non-Pneumatic Tires (NPTs) are designed and the corresponding finite element models of non-pneumatic tires are established respectively. Then, the static mechanical properties of NPTs are analyzed, including the bearing capacity of NPTs and the stress distribution of NPT components. Finally, the dynamic mechanical properties of gradient-free and gradient NPTs are simulated. The stress characteristics and rolling characteristics of the gradient to the key components of NPTs under dynamic load are analyzed. The results show that different gradients have effects on the radial stiffness of the tire, the maximum stress distribution position of spokes, tire rolling characteristics, and the stress characteristics of other parts of NPTs. The research results provide guidance for the structure design and optimization of non-pneumatic tires.

带梯度蜂窝结构的非充气轮胎的机械性能分析

非充气轮胎具有安全性高、承载能力强等优点，在工程应用中具有广阔的潜力。本文研究了不同梯度角对蜂窝辐条结构静态和动态性能的影响。首先，根据不同梯度和无梯度设计了非充气轮胎（NPT），并分别建立了相应的非充气轮胎有限元模型。然后，分析非充气轮胎的静态力学性能，包括非充气轮胎的承载能力和非充气轮胎部件的应力分布。最后，模拟了无梯度和有梯度 NPT 的动态力学性能。分析了在动载荷作用下梯度对 NPT 关键部件的应力特性和滚动特性。结果表明，不同梯度对轮胎径向刚度、辐条最大应力分布位置、轮胎滚动特性以及 NPT 其他部件的应力特性均有影响。研究结果为非充气轮胎的结构设计和优化提供了指导。
