Forced vibration is when a time-varying disturbance (load, displacement or velocity) is applied to a mechanical system. The disturbance can be a periodic and steady-state input, a transient input, or a random input. The periodic input can be a harmonic or a non-harmonic disturbance.

What is force vibration and resonance?
An object when forced to vibrate at a certain frequency by an input periodic force, is called forced vibration. Resonance occurs if the object is forced to vibrate at its natural frequency.
What is the equation of forced vibration?
For example, the forcing F ( τ ) = e − i ω 1 τ prescribes the excitation frequency of ω = ω0 + ɛω1.
What is forced vibration example?
Forced vibrations occur if a system is continuously driven by an external agency. A simple example is a child's swing that is pushed on each downswing. Of special interest are systems undergoing SHM and driven by sinusoidal forcing.
