Numerical study of selected military vehicle chassis subjected to blast loading in terms of tire strength improving

Abstract

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.

Grounding Characteristics of a Non-Pneumatic Mechanical Elastic Tire in a Rolling State with a Camber Angle

“…structure of a tire and its complex force and rolling conditions in the process of interaction with the pavement [13] and [14]. To deeply study the mechanical properties of tires, researchers have carried out a great deal of theoretical and experimental work and achieved fruitful results [15] to [17]. Song et al [18] studied the temperature distribution of a tire under the rolling condition by the FE method.…”

On the validation of the LS-DYNA Geo Metro numerical model

“…The vehicles used in [8][9][10][11][12][13][14][15][16] contained a simplified wheel model that proved to be sufficient for the most cases. More detailed wheel modelling approach has been used in papers [17][18][19][20][21][22][23]. As observed in a large number of full-scale crash tests many cars end up with broken suspension as well as damaged tire or wheel.…”
