Purpose <p>This study aims to investigate the dynamic response of a cantilever beam subjected to the influence of a rotating mass, with an emphasis on understanding how rotating mass parameters affect vibration characteristics.</p> Methods <p>A discretized theoretical model was developed to predict natural frequencies and amplitude responses under varying configurations. Experimental validation was conducted using a controlled setup, where the position of the rotating mass and the stiffness of the attached spring were systematically varied.</p> Results <p>Both theoretical and experimental results reveal that vibration amplitude strongly depends on the position of the rotating mass. Amplitude is significantly reduced when the mass is placed near the fixed or free end and reaches a maximum near the beam’s mid-span. Strategic placement of rotating components can be employed as an effective method for vibration control in cantilever structures. This has potential applications in vibration mitigation for rotating machinery and structural health monitoring.</p> Conclusion <p>The study provides an integrated approach, combining theoretical modelling and experimental validation, to address a common yet underexplored problem in structural dynamics. The results contribute to improved design strategies for vibration control in mechanical and structural systems.</p>
