传统的弧形闸门的支臂结构基本上都是三角架式的，这主要是因为按平面体系进行计算的传统设计方法忽略了结构的整体性及弧形闸门的空间结构特点，设计得比较保守，而实际上，将其改为a型结构也存在可行性，本文是利用有限元分析软件? ? ansys对原模型及修改模型分别进行静态和固有频率的计算，通过分析比较其结果可知，支臂改为a型后会使闸门的整体受力趋于均匀，即原模型受力大的部件其应力变小，而原模型受力小的部件其应力会变大；而且a型支臂的支杆在不同的放置位置对支臂的应力和位移变化也有一定的影响。 | | 7. | The characteristics of the intrinsic frequency distribution of the framed steam turbine - generator set foundation are summarized ; it can been seen that the base plate of the framed foundation does not have much effect on the dynamic response of the foundation , and that the " amplitude method " is better than the " resonance method " among dynamic analysis methods . when designing a framed foundation , as long as the load - bearing capacity and stability is ensured , a flexible pillar is better , the amplitude of vibration can be controlled through adjusting the particle quality in foundation design
