| 中文摘要: |
| 根据圆柱谐振腔频率公式,选择模式数大于或者等于10、简并比为0的 10组谐振腔尺寸,运用COMSOL软件对选定谐振腔内轮胎微波硫化过程进行数值模拟,得到微波硫化过程中轮胎的温度分布、体平均温度、微波利用率及最大温差,对结果进行分析发现：体平均温度与微波利用率呈现良好的一次函数关系；半径652mm、高度470mm的圆柱谐振腔内的轮胎最大温差最小,轮胎加热也最为均匀,加热效果最优,所以确定最终圆柱谐振腔的半径为652mm,高度为470mm。 |

| According to the formula of cylinder resonator frequency, 10 different sizes of resonator with the mode number equal to or greater than 10 and degeneracy ratio as 0 were chosen. After numerical simulation of tyre during microwave vulcanization process in a given resonator by the COMSOL Multiphysics, some statistics were gained, including temperature distribution of tyre, average temperature of tyre, microwave utilization and the maximum difference of temperature. Analysis on these statistics contributed to the finding that the average temperature of tyre and microwave utilization present linearity; The resonator with 652-millimeter-long radius and 470-millimeter-long height enabled tyre to get the lowest maximum difference of temperature, the highest uniformity of temperature distribution and the best heating performance. As a result, the final radius was identified as 652mm, and the height as 470mm. |
