چکیده: Abstract: Non-pneumatic tires are considered as a viable alternative to pneumatic tires due to their distinctive features and advantages. Extensive research has been conducted to investigate the properties and parameters that affect their performance. In this project, the spokes of a non-pneumatic tire were examined using Abaqus finite element software to evaluate their impact on overall tire performance. The study focused on key design parameters including vertical stiffness, maximum stress in the spokes and the entire tire, contact pressure, and the weight of the structure. The optimization process involved utilizing mini tab software and the DOE method to identify the most suitable spoke layer structure. The primary objective of this project was to design and model new spoke layer structures for non-pneumatic tires, surpassing the limitations of previous models. Novel auxetic structures were proposed to achieve this goal. A comprehensive parametric study was performed to analyze various structures and influencing factors such as loading type and cell wall thickness. These structures were evaluated under static load conditions and compared with pneumatic tires of similar nature. Ultimately, the most effective structures with the highest load-carrying capacity, offering optimal conditions for replacing standard pneumatic tires, were identified
