Abstract
This study aims to investigate the relationship between the static characteristics of non-pneumatic tires (NPTs) and spoke design parameters using the finite element (FE) method. A three-dimensional FE model of the NPT was established. The influence of different ranges of stress and strain on the calculation accuracy of the Neo-Hookean and Yeoh constitutive models was analyzed. Subsequently, the main design parameters—spoke thickness, spoke number, and arc curvature—were selected according to the geometric characteristics of the spokes. The effects of these three parameters on the vertical stiffness, maximum spoke stress, overall maximum stress, and maximum and average contact pressures were examined using univariate and multivariate analysis methods. The range and variance analysis results indicated that the spoke thickness, spoke number, and arc curvature had a significant effect on the vertical stiffness. Finally, the relationship between the vertical stiffness and product of the spoke thickness and number was obtained using a nonlinear fitting method. When the arc curvature of the spoke was less than 5 m−1, the errors between the calculated and simulated vertical stiffness did not exceed 5%. This observation can be used to facilitate the rapid design of spoke parameters under different load capacity requirements.
期刊介绍：
Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance.
Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
