Abstract

Abstract: The paper deals with modelling and testing of a logistic trucks supporting military operations tyre under strongly dynamic loading conditions. A detailed discrete model of a tyre was developed and validated with the actual one. As a consequence, the blast loading tests were carried out taking into consideration two different explosive distance of the tyre tread. The tests were repeated using numerical methods. During the investigations, a characteristic of tyre structure destruction was compared and the pressure distribution in numerical simulations was analysed. In the finite element modelling, the Simplified Rubber constitutive model, available in commercial LS-Dyna code, was implemented with material characteristics obtained experimentally. The mechanical properties of rubber were assessed within various strain rates: from quasi-static conditions to strongly dynamic ones. Considering erosion in an FE model, the results obtained from comparison with the actual wheel (tyre) showed good accuracy. Graphical abstract: Highlights: Detailed FE model of the tyre was developed. The proposed method of cords-tyre modelling is original and novel. The proposed model was validated with actual one in strongly dynamic conditions. Dynamic response of the tyre and its failure was examined. Detailed studies oriented on FSI local effects were conducted.
