| 中文摘要: |
| 根据实际温模载荷，利用有限元分析软件对9.00R20和12.00R20全钢子午线轮胎活络模具进行传热模拟分析。结果表明：原模具花纹块表面上侧温度比下侧温度高，最高温度出现在花纹块中间偏上位置；弓形座角度减小，花纹块表面温差增大；改变上盖闭滑板结构、中套气室位置、花纹块与弓形座配合方式及弓形座材料，花纹块表面温差变化不大，但是花纹块厚度对花纹块表面温差影响较大。 |
| 英文摘要: |
| 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. |
