WebThe Classical Undamped Tuned Dynamic Absorber. A sinusoidal force F 0 sin w t acts on an undamped main mass-spring system (without the absorber mass attached). When the forcing frequency equals the natural frequency of the main mass the response is infinite. This is called resonance, and it can cause severe problems for vibrating systems. http://howellkb.uah.edu/public_html/DEtext/Part3/Springs2.pdf
