摘　　要：基于模块化建模方法开发了汽包水位晃荡的水动力学仿真模型,研究了汽包水位晃荡周期与汽包水位之间的函数关系,汽包水位晃荡周期与汽包尺寸之间的函数关系,以及液体密度和模块划分数目对汽包水位晃荡与波动的影响等,并采用容器里液体晃荡频率解析解理论对模型的正确性进行验证,结果表明:仿真模型可以动态地反映容器里液体的固有晃荡规律,为建立完整的汽包水位晃荡模型与开发先进的汽包水位控制策略奠定了基础。　The hydrodynamic simulation model of drum level wave action and sloshing was developed based on the method of modularization modeling.The functional relationship between the sloshing cycle of drum level and the drum level,as well as that between the sloshing cycle of drum level and the drum size is analyzed,and the influence of the liquid density and the sub-module number on the drum level wave action and sloshing is studied.The analytic solution theory of liquid′s wave action and sloshing in the container was useded to validate the model,and the results show that the simulation model can reflect the natural wave action and sloshing rules of the liquid in the container.
