【 摘 要 】

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.
