Research on Optimizing the Stirrer of Reverberation Chamber Base on the Two-way Analysis of Variance

针对混响室搅拌器的优化问题,建立了混响室仿真模型,分析了搅拌器叶片不同夹角和不同边长比对混响室场均匀性的影响,得到了叶片较优夹角和较优边长比。通过对仿真数据进行双因素方差分析,得到搅拌器叶片夹角和边长比对场均匀性影响的权重关系。该结论为混响室搅拌器的优化设计提供了指导依据。

Aiming at the problem optimizing the stirrer of reverberation chamber, the simulation model of reverberation chamber was proposed. This paper analyzed the different blade angles and the different side length ratios of stirrer how to influence uniformity of reverberation chamber, gave the preferable blade angle and side length ratio. By the two-way analysis of variance, the weight relationship of the two parameters was obtained. The result would provide technical guidance for optimizing the stirrers of reverberation chamber.
