摘要
The authors present a multistage testing procedure for a truck tyre. Quasi-static, dynamic and strongly dynamic tests were carried out including: radial deflection test, bounce test and blast loading test. Results from experiments and finite element analyses were compared and showed acceptable accuracy in terms of deformation (first and second tests) and failure (third test). A novel and detailed discrete model of the tyre was developed for simulations with cord arrangements that realistically correspond to the actual tyre. Firstly, however, the experimental material properties assessment is discussed with a special attention on rubber parts of the tyre. The tabulated Simplified Rubber Material model was used for simulating the hyperplastic behaviour of the tyre. A number of tests were conducted from the lowest strain rate to the highest to obtain the required stress-strain curves for the tyre rubber. Quasi-static uniaxial tests were carried out, whereas experimental tests under dynamic conditions were performed using the Split Hopkinson pressure bars (with aluminium alloy Al 7075-T6 and polymathic methacrylate bars). Moreover, rubber material properties were correlated with experimental test data. The proposed methodology can be very useful in tyre modelling in static problems as well as in those where dynamic effects play an essential role. (C) 2016 Elsevier Ltd. All rights reserved.
