natural frequency


natural frequency
1) natural frequency of a body or system is a frequency of free vibration.
2) a frequency where a system resonance exists. If excited at this frequency, the system will exhibit very large displacements (for low damping levels). If the system is undamped, then vibrations can occur at the natural frequency without any external excitation indefinitely.
