摘要
本文提出采用有限元板壳单元模型来模拟大型汽轮发电机若干部件的力学分析模型,通过理论与有限元计算分析可见,采用这样的模型,可以简化模型的建立,简化计算,并能取得与理论上加筋用梁模型所获得的效果和计算精度.本文提出的简化模型有效性已经在若干发电机力学问题的分析中获得验证.
In this paper, an approach of finite element analysis to some parts of large turbine generators is proposed by using plate/shell element instead of beam element for stiffness beam on the shell. The simplified model and calculation procedures can be obtained. Examples are given to show the effectness of the proposed approach in the design of generators.
