Simulation of temperature field and optimisation of high-temperature parts for a giant mine tire

The temperature field of tires has a significant impact on the cracking aging and service life of tires. Therefore, the finite element simulations of the temperature field of the mining tire were carried out in this paper. The temperatures of the key parts of the tire were measured with the thermocouple under real working conditions. The deviation between the results of the simulation and the measurement is 1.3%. In addition, the function among the maximum temperature, the velocity and sinking amount of the tire was fitted using the simulating results of the temperature field under the nine types of working conditions. Further, based on the response surface method, the structure of the 1# strap layer with high temperature of the tire was optimised by taking the width of the strap layer, the distribution density of the steel wire and the angle of the steel wire arrangement as the independent variables, and the maximum temperature of the tire under steady rolling as the response value. Finally, the results show that the maximum temperature of the optimised model decreases by 3.06 °C compared to the original model.
