Natural frequency and forced frequency

WebNatural modes will be excited either by principle when the system is freely vibrating or by an external force when its frequency coincides with the natural frequency corresponding … If the forced frequency is equal to the natural frequency, the vibrations' amplitude increases manyfold. This phenomenon is known as resonance. In analysis of systems, it is convenient to use the angular frequency ω = 2πf rather than the frequency f, or the complex frequency domain parameter s = σ + ωi. In a … Ver más Natural frequency, also known as eigenfrequency, is the frequency at which a system tends to oscillate in the absence of any driving force.
