Turbo generator foundations are critical structural systems designed to safely support heavy rotating machinery subjected to continuous dynamic loading. The performance, stability, and operational safety of turbo generators largely depend on the behaviour of their foundations under vibration and dynamic forces generated during machine operation. Improper foundation design may lead to excessive vibration, resonance, structural cracking, settlement, and premature failure of machine components. Therefore, dynamic analysis and vibration control are essential aspects in the design of machine foundations. The present study focuses on the parametric analysis and design of turbo generator foundations with different footing geometries using ANSYS software. Various foundation configurations such as square, rectangular, circular, and oval footings having the same volume are considered to evaluate their structural and dynamic behaviour under machine-induced loading. The study investigates important response parameters including natural frequency, displacement, vibration amplitude, stress distribution, stiffness characteristics, and resonance behaviour. A detailed review of previous research indicates that the seismic and dynamic performance of turbo generator foundations is significantly influenced by foundation geometry, soil-structure interaction, embedment depth, machine mass elevation, and damping characteristics. Advanced analytical approaches such as finite element analysis, modal analysis, harmonic analysis, response spectrum analysis, and timehistory analysis are widely used to evaluate the realistic behaviour of machine foundations under static and dynamic loading conditions. The literature also highlights the importance of avoiding resonance by maintaining sufficient separation between machine operating frequency and foundation natural frequency. The study further emphasizes the role of modern computational tools such as ANSYS, STAAD.Pro, and other finite element software in accurately predicting the dynamic response of machine foundations. Comparative analysis of different footing shapes is carried out to identify the most efficient geometry in terms of vibration control, structural stability, and load distribution while maintaining equal footing volume. The findings of the study are expected to provide a systematic understanding of the influence of footing geometry on turbo generator foundation performance and contribute toward the development of safer and more economical machine foundation design practices.
