WebJul 27, 2024 · Figure 15.5. 1: A mass-spring-damper system with an external force, F, applying a harmonic excitation. Consider the system above. The equation of the system becomes: (15.5.2) ⇒ x ¨ + c m x ˙ + k m x = F 0 m sin ( ω 0 t). Because the natural vibrations will damp out with friction (as mentioned in undamped harmonic vibrations ), … WebApr 9, 2024 · If there is a restoring force, the vibratory motion of any system will continue indefinitely if there is no resistance force. Friction will reduce the mechanical energy of this system, and this is what is referred to as damped vibration. The damping will then reduce the amplitude of the vibrations progressively.
