Research on Discrete Data Analysis of Vehicle Retread Tire Performance Based on Radial Stiffness Method

The retreaded tires of transportation vehicles often cause delamination and tearing of the tread and carcass due to the temperature rise of the tires. For the failure analysis and rational use of the retreaded tires, a steady-state thermal analysis model of the retreaded radial tires in the rolling state is established and carried out the temperature measurement test. On this basis, the numerical simulation, simulation calculation and experimental analysis of the thermal-structure coupling field are carried out, which truly reflects the thermal stress status of the retreaded tire.
