Abstract: In order to investigate the basic mechanical properties of the Uptis non-pneumatic tyre, this paper refers to the Uptis prototype tyre for modelling and its composite load-bearing characteristics are studied in detail. Based on ABAQUS software, the three-dimensional model and numerical analysis model of the Uptis non-pneumatic tyre are established, and the mechanical properties are analysed under the radial force only, and under the composite force. The results show that the stiffness characteristics, grounding pressure distribution law, and the stress-deformation characteristics of the flexible spoke non-pneumatic tyre ensure that the tyre has both cushioning and damping performance on the basis of excellent load-bearing characteristics. The research work of this paper provides a certain theoretical reference for the structural optimisation and practical application of the Uptis non-pneumatic tyre.

Keywords: non-pneumatic tyre; Uptis non-pneumatic tyre; mechanical properties; composite load-bearing characteristics; numerical analysis; stiffness characteristics; radial stiffness; lateral stiffness; longitudinal stiffness; grounding pressure distribution law; stress-deformation characteristics.
