“…Some reports suggest that in spoke-based designs, the ride comfort of vehicles can be improved by reducing the thickness of the flexible spokes. Rugsaj and Suvanjumrat 93 carried out tensile and compression tests on an NPT to find a suitable hyperplastic material model and verified its adequacy with experimental procedures. Studying the relationship between radial stiffness and spoke thickness, Rugsaj and Suvanjumrat 83 used numerical methods to optimise the spoke thickness for NPTs.…”

The interest in airless or non-pneumatic tire (NPT) structures emerges due to potential performance and environmental advantages, such as reduced rolling resistance and improved recyclability, when compared with traditional rubber-based pneumatic tires. NPTs can already be found in commercial applications such as forklifts, electric scooters, and wheelchairs. Even so, up to the knowledge of authors, there is no known established large-scale production of NPTs for most applications. This work presents a systematic literature review regarding the mechanical design and development of NPTs. A summary of structural characteristics and mechanical behaviour analysis is provided. Relevant standards, analysis strategies, materials, production techniques, and the end-of-life of tires are addressed. In the end, the authors debate the current challenges and prospects of these emergent products. Furthermore, this research aims at being used as a tool, potentiating the development of innovative and efficient, airless tire solutions. The review presented clarifies that many academic efforts are focused on finding optimal functional designs, which are frequently complex and physically demanding. These geometrically complex design proposals are, in most cases, composed of intricate cellular structures and spokes arrangements. Based on the current lack of knowledge, authors identify key research areas to be further developed such as the production, performance, and reliability of NPTs. It is debatable whether there will ever be a shortcoming of the rubber tire, or a time when fully recyclable tires are a societal obligation. Nevertheless, the number of reasons to promote the development of a reliable replacement to the traditional tire is far from scarce.

“…Ma et al [10] studied the strain (stress) between soil and treaded NPTs with varying shear bands of different cell geometries through finite element analysis and determined the appropriate cell angle, cell height, and leg length. Rugsaj et al [11][12][13][14][15][16] conducted a systematic study of the Tweel. The material parameters of the spokes were determined via a three-point bending test and uniaxial tension and compression tests, and the precision of the material constitutive was confirmed through simulation.…”

A high load capacity non-pneumatic tire (HC tire) was designed and manufactured to solve the problems of air leakage, puncture, blowout, shoulder void, and delamination, which occur in traditional high load capacity tires, as well as significantly increase the unit load of tires. Experiments and numerical simulations were conducted to investigate the static stiffness properties of the HC tire. Additionally, the manufacturing process of the tire was highlighted. The tire mainly comprised polyurethane and silicon manganese steel, and a ‘π’-shaped support substructure was adopted. The tread structure was made up of a built-in spiral steel ring and a non-steel ring. The uniaxial tensile mechanical properties of the used metal and elastomer materials were tested, and the linear elastic constitutive model and Marlow constitutive model, respectively, were used to describe their mechanical characteristics. The stiffness properties of the HC tire, including torsional, longitudinal, vertical, and lateral stiffnesses, were evaluated using a tire comprehensive stiffness tester. Nonlinear finite element models of the HC tire were established, and their accuracies were verified through vertical stiffness tests. The stiffness properties of the HC tire in other directions were simulated as well. An in-depth comparative analysis of the simulation and experimental data was performed. The results demonstrated that the unit load of the unreinforced HC tire was 2.972 times and 1.615 times higher than that of the solid tire and pneumatic tire, respectively. The spiral steel ring embedded in the tread increased the vertical and longitudinal stiffness but reduced the torsional stiffness of the HC tire, thus reversing the variation trend of the lateral stiffness at the 0° and 5° test points. The findings can serve as a reference for theoretical research on, and the structural optimization of, non-pneumatic tires with a high load capacity.

“…Rubbers are widely used in military, food, automotive, and medicine due to their convenient mechanical behavior [1]. The main applications consist of tires, seals, gaskets, shock and vibration absorbers, medical devices, and electrical insulators [1][2][3]. Rubbers usually demonstrate an incompressible hyperelastic behavior [5].…”

This study aims to experimentally compare the elasto-mechanical behaviors of ethylene propylene diene monomer rubber (EPDM), neoprene rubber, silicone rubber, and natural rubber. Rubbers were tested under uniaxial, equibiaxial, and planar loading for five different samples of each material, and the average values have been calculated. Based on the experimental results, a rubber identification was performed by using different rubber models such as Ogden, Mooney-Rivlin, etc. presented in the literature. The result of this study demonstrated that the EPDM rubber showed the highest stress value compared to the other rubbers, silicone rubber, and natural rubber showed similar behavior. Moreover, Neoprene rubber showed the lowest stress value.
