摘要
应用有限元分析软件ANSYS建立了900 MW汽轮发电机端盖式轴承座有限元分析模型,并对此轴承座刚性进行了计算分析,获得了900 MW汽轮发电机端盖式轴承座刚度的量化概念。初步研究了轴承支承系统的刚度及其对900 MW汽轮发电机轴系动特性的影响。
The rigidity of an end-bearing pedestal＇s model, destined for a certain type of 900 MW turbo-generator, is being analyzed by using the finite element analyzing software ANSYS, and a theoretical solution model subsequently found. The influence of the pedestal＇ s rigidity on the dynamic characteristics of the rotor string is beinig studied in addition.
