Effect of frame foundation geometry on the dynamic response of high-speed turbo machine foundations.

The foundation of the turbo-generator comprises a generator, turbine, and associated equipment situated on the top of the frame foundation, which consists of a bottom raft, top deck, and columns. The current study examines how the geometrical characteristics of the frame foundation, such as slab thickness, column dimensions, and length, affect the dynamic displacement response and the natural frequencies of the frame foundation. The work is done through 3-D dynamic modal and harmonic analyses using Ansys Workbench finite element software.
