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：
The International Journal of Automotive Technology has as its objective the publication and dissemination of original research in all fields of AUTOMOTIVE TECHNOLOGY, SCIENCE and ENGINEERING. It fosters thus the exchange of ideas among researchers in different parts of the world and also among researchers who emphasize different aspects of the foundations and applications of the field.
Standing as it does at the cross-roads of Physics, Chemistry, Mechanics, Engineering Design and Materials Sciences, AUTOMOTIVE TECHNOLOGY is experiencing considerable growth as a result of recent technological advances. The Journal, by providing an international medium of communication, is encouraging this growth and is encompassing all aspects of the field from thermal engineering, flow analysis, structural analysis, modal analysis, control, vehicular electronics, mechatronis, electro-mechanical engineering, optimum design methods, ITS, and recycling. Interest extends from the basic science to technology applications with analytical, experimental and numerical studies.
The emphasis is placed on contributions that appear to be of permanent interest to research workers and engineers in the field. If furthering knowledge in the area of principal concern of the Journal, papers of primary interest to the innovative disciplines of AUTOMOTIVE TECHNOLOGY, SCIENCE and ENGINEERING may be published. Papers that are merely illustrations of established principles and procedures, even though possibly containing new numerical or experimental data, will generally not be published.
When outstanding advances are made in existing areas or when new areas have been developed to a definitive stage, special review articles will be considered by the editors.
No length limitations for contributions are set, but only concisely written papers are published. Brief articles are considered on the basis of technical merit.
