145579 - Comparative Analysis of Non-Pneumatic Tire Spoke Designs for On-Road Applications: A Traction Force Perspective 

This study explores the traction performance and structural integrity of Non-pneumatic (NP) tires, which are being explored as alternatives totraditional air-filled tires, offering enhanced durability, reduced maintenance, and improved eco-friendliness. This study investigates the influenceof four spoke shapes (honeycomb, modified honeycomb, re-entrant honeycomb, and straight spokes) on NP tire traction performance for on-roadapplications. Using Finite Element Analysis (FEA), the study considers the influence of longitudinal speed and vertical load on the tractionperformance and stress distribution of the NP tire designs. This assessment of traction coefficient under the constant torque will reveal distinctvariations in performance across the four-spoke designs. By systematically varying these parameters, the study aims to provide a detailedunderstanding of how different design factors influence the overall performance of NP tires. Furthermore, the traction coefficient measurementshelped to identify spoke configurations that optimize tire-road interaction performance. Comprehensive comparison and evaluation of the four NPtire spoke designs highlight their respective advantages and limitations for on-road applications.
By optimizing spoke shapes and considering theeffects of speed and load, manufacturers can develop NP tire designs that offer improved traction, durability, and efficiency for a wide range ofautomotive applications. These findings provide valuable insights for optimizing NP tire designs, aiding decision-making for manufacturers in the automotive industry.
