Transient vibration refers to the vibration caused by external transient excitation.Transient process is an all embracing non periodic deterministic process, whose basic feature is a short duration burst process, such as aircraft landing, gun launch, explosion, earthquake, collision and impact, which will trigger transient vibration.The characteristics of transient vibration are often studied and analyzed by transforming transient vibration in time domain into frequency spectrum in frequency domain through Fourier transform.[1]

Properties
physical phenomenon
Transient vibrationIt is the vibration caused by external transient excitation.The general vibration system is damped, so the transient vibration attenuates with time.Strictly speaking, such vibration is no longer simple harmonic vibration, so the meaning of amplitude, frequency and period is inaccurate.
