“…Immersed in the rubber with different orientations, they form a special ring-like laminate. One can find that most authors use a simplified technique [18,19] or complex method [20,21] for tire discretization, both with overall good correlation with the experiments.…”

Abstract. In the paper a chosen model of the light armoured vehicle was tested in terms of blast loading. More precisely, the blast propagation and interaction with the tire behaviour and suspension system elements of the light-armoured vehicle (LAV) was simulated. The chosen military vehicle meets the requirements of levels 2A and 2B of STANAG 4569 standard. Based on the obtained results, two modifications were proposed for the strength and resistance improvement of the wheel. The first consisted of inserting the rubber runflat ring inside the tire, whereas in the second the honeycomb-like composite wheel was implemented. Non-linear dynamic simulations were carried out using the explicit LS-Dyna code, with multi-material Arbitrary Lagrangian-Eulerian formulation for simulation the blast process.

“…FE analysis discretizes the continuous geometric structure into finite elements and sets finite nodes in each element; thus, the continuum is discretized into a set of elements connected by nodes. The FE method has been an essential part of tire research, and various mechanical properties of the tire can be analysed according to different material properties, geometric contours, loads and boundary conditions [28] and [29].…”

A non-pneumatic mechanical elastic tire (ME wheel) was introduced, and the grounding characteristics of the ME wheel under a rolling condition with a camber angle were investigated with the combination of finite element simulation and experimental research. According to the ME wheel structure and material characteristics, a numerical simulation model of the ME wheel was established using the finite element (FE) method. The stiffness tests were carried out to verify the accuracy of the simulation model of the ME wheel. To highlight the advantages of the ME wheel, an inflatable tire was selected as the reference tire, and the grounding characteristics of these two tires with different camber angles were compared and analysed in free rolling, braking, and driving conditions. Different slip ratio values for the ME wheel and inflatable tire were applied in driving conditions to analyse the influence of the slip ratio on the grounding characteristics. The obtained results indicated that both the ME wheel and inflatable tire will gradually suffer partial wear of the tread surface as the camber angle increases, but the pressure concentration of the inflatable tire is more serious. The research can provide a basis for structural optimization and comprehensive mechanical performance analysis of the ME wheel.

“…Due to having the long chain molecule, rubber material usually presents a complicated mechanical characteristics which cannot be described by the linear elastic theory and has large deformations, plastic and viscoelastic properties [18][19][20][21]. As a typical hyperelastic material,the rubber can be defined by a stored energy function [2]. The characterization of rubber should be determined by various experimental data, so the key issue is to acquire a reliable material model which can provide good fit with the test data.…”

“…It is of great importance to ensure that the numerical calculation can simulate the response of the rubber material. To get reliable and accurate characteristics of rubber material, many researchers did lots of works on fitting and comparison of rubber models with experimental data [2,13,22,23]. ANSYS/LS-DYNA has many material models to define the rubber material, including Mooney-Rivlin, Frazer-Nash, Simplified Rubber Material, Hyperelastic and Yeoh model, etc [24].…”

According to relevant airworthiness standards, the aircraft fuel tank access cover must withstand the impact by tire fragments, and minimize the penetration and deformation, which is critical for flight safety. To assess the safety of an aircraft fuel tank access cover subjected to tire fragments, a study of dynamic response was presented in this paper using the Finite element (FE) software ANSYS/LS-DYNA. To obtain the reliable mechanical characteristics of tire tread rubber, a series of material tests have been conducted. Then the proposed rubber material model is validated by comparing the numerical simulations with the experimental results of aluminium alloy plate impact. The simulation results indicate that the rubber fragment and alloy plate will undergo the largest deformation when impact angle is equal to 90°. Finally, the proposed FE model and modelling approaches are extended to the numerical simulation of a full-scale aircraft fuel tank access cover impact. The numerical simulations are carried out with impact velocity of 71.1 m/s and impact angle of 40.5°. The simulation results indicate that the aluminium alloy by precision casting is more likely to rupture, and the middle region of the access cover is vulnerable to fragment impact. This research proposes a reliable rubber model applying to various strain rates. Considering the influence of impact regions, the dynamic response and various failure patterns of fuel tank access cover are acquired. The findings of this paper can be used to improve the future aircraft safety design. which permits unrestricted use, distribution, and reproduction in any medium, provided you give appropriate credit to the original author(s) and the source, provide a link to the Creative Commons license, and indicate if changes were made.
