Abstract

Abstract: A new non-inflatable all-metal tire structure is designed to prevent the tire burst due to puncture and shrapnel penetration. Theoretical models of vertical stiffness prediction and vertical vibration are established. A tire simulation model is built using 3D modelling software Pro/E, finite element preprocessing software ANSA and fimite element simulation software Abaqus. A metal tire prototype which has the same size as the pneumatic tire (235/70 R16) was made, and the plate loading test and vehicle ride comfort test were carried out. Simulated results show that the metal tire is not plastically deformed under the action of force in each direction, which meets the strength requirement. The accuracy of the simulation process and the strong bearing capacity of the tire are verified by the vertical stiffness test results. The ride comfort test results show that the metal tire is slightly worse than the pneumatic tire in vibration damping performance, but has better grip characteristics. Key
