摘要
根据汽机基础底板的结构特点,采用三维实体单元建立了多种汽机基础实体有限元模型。模型中天然地基采用等效弹簧单元,并考虑了不同的基础底板形式及厚度影响,以及汽机设备、基础结构和地基土协同工作。对汽轮发电机基础进行动力谐响应分析,得到了各类汽机基础的最大振动线位移,探讨了不同种类基础的动力响应,为汽机基础设计提供参考依据。
Based on the sole-plate＇ s form of turbine-generator unit foundation, a variety of turbine foundation has been researched with three-dimensional solid finite element. The spring element are employed to imitate the ground soil, the effect of sole-plate＇ s form and thickness are considered, and the turbine, basic structure and fotmdation soil are cooperation. Dynamic analysis of harmonic response for turbine-generator foundation is studied. The displacement amplitude of turbine foundation was got, the dynamic response of all kinds of foundation are discussed. References for the design of similar projects are provided.
