Application of non-pneumatic tire (NPT) has been increased during the last decade. The aerodynamic characteristics of the wheel with NPT has been studied due to significance on improvement of handling and reduction of fuel consumption. In this paper, first, an original NPT model was simulated by CATIA software, and the influence of NPT structural parameters on aerodynamic characteristics was studied by Fluent software. The simulation calculation results showed that: the reduction of tire width and spoke length, and the increase of spoke thickness can effectively decrease aerodynamic coefficient. Then, the MIRA model was used to study the influence of NPT on aerodynamic characteristics of the whole vehicle under driving conditions. Studies showed that: NPT increased the resistance of the whole vehicle, and 63.1% of the resistance at the wheels was provided by the front wheels. Finally, the wind tunnel test was conducted to study aerodynamic characteristics of the optimized NPT model under static conditions and verify the simulation calculation.

“…Nevertheless, the pneumatic tires are prone to safety issues, such as perforations, punctures, and bursts under harsh conditions, greatly affecting traffic safety. 1 To satisfy the urgent requirements of vehicle safety, various safety tire technologies such as “Tweel,” 2 “Air free,” 3,4 and “honeycomb wheel” 5,6 have been developed by tire manufacturers and researchers. These non-inflatable wheels eliminate the safety problems related to tire pressure, because the hub and tire are connected through a special material with a certain structure and the wheel has no gas in it.…”

“…7 In the past, the static and dynamic characteristics of an ME-Wheel have been investigated deeply and its few potential advantages in some respects over a pneumatic tire were demonstrated in previous studies. 1,8–11 ME-Wheel not only have the basic functions of pneumatic tires but also eliminate the dangers of pressure deflating and blowouts, because the inflatable structure of a pneumatic tire is substituted by the flexible hinge groups.

The tire/soil interaction is an important and complex research topic in vehicle-terrain mechanics, which has a great influence on vehicle mobility and soil compaction. The purpose of this work was to develop a detailed nonlinear finite element model for parametric analysis of the interaction between mechanical elastic wheel and the soil. The three-dimensional finite element model of the mechanical elastic wheel, which considers material nonlinearity, geometric nonlinearity, as well as large contact deformation between the mechanical elastic wheel and soil, was developed based on the physical model. The reliability and accuracy of the finite element model were validated by comparing the predicted wheel static loading characteristics in rigid plane with those of experiments. The finite element model of the soil is modeled as a two-layer system and the Extended Drucker–Prager model was used to describe the nature soil properties. The deformation and stress of the soil and mechanical elastic wheel under the static loading condition were studied in detail. Moreover, the effects of the axial load on mechanical elastic wheel/soil interaction were also analyzed. The research results could offer reference for an optimum structural design of a mechanical elastic wheel and a prediction of soil compaction caused by non-pneumatic tires.

A non-pneumatic tyre (NPT) is a novel type of safety tyre that is designed to provide similar elastic properties to those offered by conventional pneumatic tyres. The main advantage of NPT is the lack of compressed air (like in a pneumatic tire) to ensure adequate traction forces and directional control. Suitable materials and the appropriate geometry of the supporting structure allows to achieve properties provides by pneumatic tires. Flexible spokes and closed structure like honeycomb are the most common solutions of supporting structure. Appropriate geometry, thickness and materials of this part affect the NPT properties; radial stiffness, unit pressure in the contact patch and the parameters of an area in contact with a non-deformable surface. The paper presents the FEM NPT model (NPT_0), which was validated with the results of experimental research of NPT. The NPT_0 model is subject to further modifications (layout and shape of the radial spokes) was used in the study. Seven new geometries of NPT supporting structure were selected for simulation tests. During the numerical tests the radial stiffness, unit pressure in the contact patch and the parameters of an area in contact with a non-deformable surface were determined. It has been observed that an increase in the curvature of the spokes reduced radial stiffness and increased the length of the contact path.
