this video gives a brief introduction to experimental modal parameter identification and then talks about the algorithm of mode isolation and show some examples of how to use the simple mat lab routine uh modal parameter identification is the process of trying to determine the modal parameters or the natural frequency damping ratios and mode shapes of the modes um in a certain system and typically we do that from a set of measurements either time domain or frequency domain here weamp;#39;ll focus on frequency domain measurements and the frequency response function Matrix Matrix h of Omega but we could also talk about time do domain measurements which um for practical purposes are usually just the inverse F of T of measured frequency responses so the basic idea is we have a set of measurements and we think that they are described by a set of modes and uh we want to determine the natural frequency damping ratio and mode shape that c that best um describe a certain set of measurements so
