Abstract

The structure of non-pneumatic tire is complex and various, but its performance is superior to ordinary tire, so it has broad prospects. In this paper, a design method of honeycomb structure was proposed based on tangent method, and the hexagonal and circular honeycomb structure were established. The rules of displacement, radial stiffness and ground pressure of honeycomb structure with different density were studied. Meanwhile, the most basic bearing performance of non-pneumatic tire was analyzed by finite element method under static conditions. The results show that the radial stiffness of honeycomb increases with the increase of density. When the density is small, the bearing capacity of circular structure is stronger than that of hexagonal structure, the ground pressure decreases with the increase of density and the maximum stress of the two is located on the honeycomb structure. When the density is high, the maximum stress is on the contact surface between the rim and the inner circumference. This study provides a reference for other types of non-pneumatic tire structure design and builds the foundation to study contact performance analysis of non-pneumatic tire under complex working conditions.

蜂窝结构非充气轮胎的结构设计及特性

摘要

非充气轮胎结构复杂多样,但性能优于普通轮胎,前景广阔。本文提出了一种基于切线法的蜂窝结构设计方法,建立了六边形和圆形蜂窝结构。研究了不同密度蜂窝结构的位移、径向刚度和地压规律。同时,采用有限元法对静态条件下非充气轮胎最基本的承载性能进行了分析。结果表明,蜂窝的径向刚度随着密度的增加而增加。当密度较小时,圆形结构的承载能力强于六边形结构,地压随密度的增加而减小,两者的最大应力位于蜂窝结构上。当密度高时,最大应力在轮辋和内圆周之间的接触面上。该研究为其他类型的非充气轮胎结构设计提供了参考,为研究非充气轮胎在复杂工况下的接触性能分析奠定了基础。
