| Abstract: |
| According to the actual temperature load，the finite element software was used to simulate the temperatures of flexible mold for 9.00R20 and 12.00R20 all-steel tires.The results showed that the temperature on the upper side of the pattern block surface was higher than that on the lower side，and the maximum temperature appeared on the upper middle of the pattern block.With the decreasing of the bowstring angle，the surface temperature difference of the pattern block increased，and it changed little by changing structure of the upper cover closed slide，the position of center sleeve air chamber，the matching way between the bowstring and pattern block and bowstring material.However，the thickness of the pattern block had a great influence on the surface temperature difference of the pattern block. |
