| Abstract：The periodic topology optimization mathematical model of tire mold base（referred to as the base） was established by taking the total volume as the design variable，and the optimization was carried out by using a variable density method，aiming at 30% reduction of the total volume and minimization of the base compliance within the optimization domain. Using the optimization model, the stress，fatigue life and heat transfer performance of the base before and after optimization were simulated and analyzed. The results showed that the maximum stress and maximum vertical displacement of the optimized base were reduced by 17. 2% and 20. 8%，respectively，the minimum fatigue life was lengthened by 2. 3%，and the temperature difference between the upper and lower end of the mold cavity pattern block was reduced from 0. 106 ℃ to 0. 081 ℃，which was beneficial to the improvement of the tire performance and service life. |
