摘　　要：根据圆柱形谐振腔频率公式,选择模式数大于或等于9、简并比为0的10组谐振腔尺寸,运用COMSOL Multiphysics软件对选定尺寸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温度分布、轮胎体平均温度、微波利用率和最大温差。数据分析表明:轮胎体平均温度与微波利用率呈现良好的一次函数关系;半径为652mm、高度为470 mm的圆柱形谐振腔内的轮胎最大温差最小,温度分布最为均匀,加热效果最优。According to the formula of cylinder resonator frequency,10 resonators with different size,mode number equal to or greater than 9 and degeneracy ratio as zero were designed. The temperature distribution and average temperature of tire,microwave utilization and maximum temperature difference during the microwave curing of tire in a given resonator were obtained by numerical simulation. The analysis on these statistics showed that,the average temperature of the tire and microwave utilization present linear relationship. The resonator with 652 mm radius and 470 mm height provided the best heating effect,and enabled the tire to get the lowest maximum temperature difference and highest uniformity of temperature distribution.
