摘要
采用有限元法对葛洲坝水轮机组的顶盖结构进行了模态以及动力响应分析,得到了结构的自振频率和相应的振型以及顶盖的动力响应结果,为机组的振动研究分析提供了指导和参考.
Based on the finite element method,the modal analysis and the transient dynamic analysis of the head cover of the water turbine set are carried out.The natural frequencies and corresponding model shapes of vibration,also the dynamic response characteristics are obtained.It is significant and referential to the vibration research of the units.
