摘　　要： 根据传统的理论计算,结合Ansys数值模拟内部电场分布,发现传统的箱型微波谐振腔设计思想不适用于设计大型微波加热装置。在此设计思想的基础上切除8个尖锐棱角并圆角化,模拟结果显示,谐振腔内部电场分布均匀性得到明显改善。比较一系列模拟结果,发现200mm半径圆角可使电场分布效果达到最佳。 In this study,it was found that the traditional design of box-type microwave cavity was not suitable for the design of large microwave heating device based on the calculation using traditional theory as well as the simulation results on electrical field distribution using Ansys.In a new design,the 8 sharp corners were changed to round corners.The simulation results on the new design showed that the uniformity of electrical field inside the cavity was significantly improved.When the corner radius was 200 mm,the distribution of the electric field was the best.
