| Abstract: | The layout position and shape of the stiffened plate structure,as well as the connection between the stiffened plate and the main structure,will affect the local stress,structural deformation,stiffness performance and natural frequency of the large parts of the hydro-generator set.This paper calculates and analyzes the concrete influence of rib plate on the local stress,structural deformation,stiffness performance and natural frequency of large components of hydro-generator set,and puts forward reasonable suggestions,which have great reference significance to the design,installation and manufacture of hydro-generator set. |
