SUMMARY
Natural frequencies, normal frequencies, and resonant frequencies are closely related concepts in vibration analysis. Natural frequencies refer to the specific frequencies at which a system tends to oscillate in the absence of any driving force. Normal frequencies are the frequencies associated with normal modes, which are orthogonal modes of vibration that can describe all possible vibrations of a system. Resonant frequencies occur when a system is driven at its natural frequency, leading to maximum amplitude oscillations. Therefore, while these terms are often used interchangeably, they have distinct meanings in the context of vibration theory.
