Abstract
This manuscript investigates vibration control in rotating machinery through the implementation of tuned mass dampers (TMDs). Rotating equipment commonly experiences resonant vibration due to unbalanced forces, aerodynamic loads, and structural interactions. Such vibrations can lead to fatigue failure, reduced performance, and safety hazards. The study presents a comprehensive methodology encompassing theoretical modeling, experimental modal analysis, and numerical simulation to evaluate the efficacy of TMDs in reducing vibration amplitudes. A statistical analysis table summarizes modal parameters and vibration reduction percentages. Simulation research using finite element models replicates real-world rotor–bearing systems, validating the experimental findings. Results demonstrate that optimally tuned mass dampers can achieve vibration reduction of up to 60% at resonance frequencies without significant weight penalties. Five specific research objectives guide the investigation. Conclusions highlight practical considerations for TMD design in industrial rotating machinery, including tuning strategies, installation constraints, and maintenance implications. All technologies and references are confined to developments up to 2014, ensuring historical accuracy and relevance to engineering discipline norms of the period.
