摘　　要：随着核电企业采用提升功率的方式提高发电效益,其内部的干燥器容易受到较高的脉动压力载荷而导致声疲劳.介绍蒸汽发生器干燥器声疲劳试验方案———行波管混响腔模型.利用计算声学软件Actran进行仿真分析,研究试验装置内部声载荷分布特征.研究结果为后续试验研究提供技术支撑.When improving the single reactor power to promote the power efficiency of the nuclear power station, the BWR steam dryer is easier to be damaged by high cycle pulsating pressure, which is called acoustic fatigue problem, acoustic fatigue experimental schemes for steam generator steam are introduced： one is the scaled model of the upper chamber of the steam generator; the other is the reverberation chamber model of the travelling wave tube. The acoustical computational software Actran has been applied to simulate the acoustic pressure distribution inside the two models. The result provides guidance for the following experimental study.
