“…The results indicated that under thermal and mechanical coupling, these properties increased compared to non-coupled conditions. They predicted a fatigue failure mileage of (2.67 × 10 4 km) for FS-NP tires using the J-integral method [18], which aligned with indoor drum test results (2.44 × 10 4 km). The study revealed that load had a more significant impact on tire temperature than driving speed, and reducing load or increasing speed could reduce high-temperature failure risks during high-speed operation.…”

“…However, pneumatic tires have several fatal drawbacks, such as catastrophic tire explosions, complex manufacturing processes, and the need to maintain internal inflation pressure [2]. In addition, pneumatic tires are often unable to withstand severe impacts and uneven road surfaces in harsh road conditions such as mines and military operations, thereby affecting the performance of vehicles [3][4][5][6]. In order to improve and overcome the shortcomings of traditional pneumatic tires, major tire companies and research institutes have increased their investment in research and development of safety tires.…”

The static and dynamic properties of the honeycomb non-pneumatic tires (NPTs) are strongly influenced by the spoke structure. Due to the complexity of the honeycomb structure, an in-depth understanding of the influences of the design parameters related to the honeycomb structure on its mechanical properties is essential, particularly for designing NPT of desired properties. Inspired by the concept of functionally graded structure, this paper aims to design a novel non-pneumatic tire with honeycomb-spoke graded thickness. Firstly, the in-plane mechanical characteristics of the thickness-graded honeycomb structures were investigated theoretically. On this basis, the finite element technique was developed for the NPTs using the corresponding thickness-graded honeycomb structures were established, and their static and dynamic mechanical properties were investigated using simulations and experimental tests. The results show that a reasonable thickness design can effectively enhance the load-bearing capacity of the NPT. The deformation features of the spoke were analyzed under the static state, and the contribution of different honeycomb structure edges deformation on the spokes is also discussed. The stress of the spoke and the tread under the static and dynamic loading conditions were studied, and comparison with the NPT-4 with a uniform thickness honeycomb structure, the results show that the thickness-graded honeycomb structure in NPT-3 significantly amplifies its load-bearing capability while also providing effective cushioning and shock absorption properties. This work would provide a basis for innovative design and performance optimization of NPTs.

“…The result shows that the high temperature zone is mainly distributed in the middle bending part of the flexible spoke unit of non-pneumatic tires, and the temperature gradually decreases from the center to the periphery. The influence of load on the temperature change of non-pneumatic tires is greater than the driving speed, which provides a theoretical basis and method guidance for solving the failure problem of non-pneumatic tires under thermodynamic coupling [ 15 , 16 ]. Many scholars have developed the influence of temperature, road conditions, pattern types, and other factors on the rolling resistance of tires.…”

Due to the viscoelasticity of rubber materials, hysteresis loss due to deformation is the main reason for the rolling resistance of high-speed rubber tracks. Since the structure and material of high-speed rubber track assemblies are different from traditional tires and metal tracks, the rolling resistance theory of traditional wheeled and tracked vehicles is not applicable. Therefore, in order to determine the rolling resistance scientifically and accurately, the mechanism research of the rolling resistance of high-speed rubber track assembly is the key to the design of high-speed rubber crawler vehicles. In this paper, the stress–strain characteristics of rubber track under the action of compression, tension, bending, and driving were studied. The strain load spectrum of rubber tracks was established, and the strain cyclic load was extracted by the rainflow method. The temperature model of the rubber track was developed based on its dynamic characteristics. On the basis of energy conservation, the hysteresis loss of rubber is equivalent to the energy consumption of rolling resistance, and the theoretical model of rolling resistance of high-speed rubber track assembly is established. In accordance with the model above, the key influencing factors and changing trends of rolling resistance are analyzed, which provides a theoretical basis for the performance optimization of high-speed rubber track assembly.
