“…In 2018, Zhao et al [34] study aimed to investigate the influence of high thermal conditions on the structural dynamic response of Mechanical elastic wheels (ME-Wheel) using a combination of FEM and Experiment Modal Analysis (EMA). The results showed that the EMA results agreed with those obtained using the FE model, indicating the high reliability of the proposed analysis method.…”

“…An ME-Wheel consists of a hub, 12 hinge groups, five elastic rings, 12 snap rings, a ﬂexible tire body, and other accessories, as shown in Figure 1. 8–11 The assembly process of an ME-Wheel is as follows. First, the elastic rings are twisted by steel wire and fixed through the snap rings evenly distributed along a circumferential direction.…”

“…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 structural design concept of ME-Wheel opens up a new route for safety tire techniques.…”

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.

Purpose A novel non-pneumatic safety tire, namely mechanical elastic wheel (ME-Wheel), has been developed recently to solve problems, including tire bursting and flat tire, of typical pneumatic tires. This paper aims to predict the life of the ME-Wheel accurately and settle the problem of lower lifespan. Design/methodology/approach This study proposes a new method to establish a novel model of virtual proving ground based on finite element analysis, and by combining with the random vibration damage analysis method, the life of an ME-Wheel is predicted precisely. Next, the weak parts and infinite life parts of the ME-Wheel are investigated from the perspective of constant life design, and an approximate response surface model is developed, which is suitable for the ME-Wheel. Then, the optimal results of the ME-Wheel are obtained, including tire modal, mass and its lifetime. Findings It is found that the proposed methods can provide a reliable theoretical basis for further improving the structural design and material selection of ME-Wheel parts. The results show that the improved ME-Wheel can reduce the weight and greatly improve the ability of anti-resonance, and the lifetime of ME-Wheel has significantly improved. Originality/value A new type of non-pneumatic tire (ME-Wheel) has been developed to avoid problems with traditional tires, such as tire leaking or puncture. A new method to establish a novel model of virtual proving ground based on finite element analysis has been proposed. The weakest key component of the ME-Wheel is determined. The life, mass and modal of the ME-Wheel are optimized.
