附加质量是研究结构在流体环境中流固耦合的一个重要参数。静水中结构振动诱导的流场附加质量，可根据势流理论，采用奇点配置法利用空间点源（汇）及偶极子基本解推导的计算式求得。利用此计算方法求得某平板闸门在静水中的振动模态，有限元计算软件Ansys自身拥有流固耦合计算模块，通过此模块可验证此计算方法对于平板闸门在工程中流固耦合求解的合理性与准确性。

Added mass is an important parameter of fluid―solid coupling of the structure in the fluid environment .According to poten‐tial flow theory ,using the singularity configuration method ,the equation of added mass from flow field induced by structural vibra‐tion which is derived from fundamental solution of spacial source (sink) and dipole can more accurately calculate the added mass of structure in the fluid .Using this calculation method ,the vibration mode of some plate gate in still water is obtained ,and the fluid―solid coupling calculation module from Ansys validates that this calculation method is reasonable and accurate for the fluid -solid coupling solution of plate gate in the engineering .
