can anyone tell what is transmissibility exactly ?
I think it's like a transfer function, but specifically for mechanical vibrations and how they propagate between two connected structures. — Preceding unsigned comment added by Chancwj (talk • contribs) 18:19, 31 May 2012 (UTC)
its nothing but isolation of vibrations.. — Preceding unsigned comment added by 122.174.95.164 (talk) 19:12, 4 February 2013 (UTC)
Transmissibility is exactly what it means it is. The degree to which what goes in musty come out! It is a dimensionless quantity. You are correct in one sense - since it is a ration of input to output, it is a bit like transfer function. But the real distinction is that it does not change the input. — Preceding unsigned comment added by Rameshdk (talk • contribs) 04:39, 7 May 2014 (UTC)
It's slightly confusing to call it the ratio of input to output, that is just a standard Frequency response function(FRF). So, for a output signal on a structure Y, and an input/ excitation signal, X, the FRF is calculated as Y/X. As the input signal is generally force, and the input is acceleration, velocity, or displacement. This is not dimensionless. Transmissibility is a different because it does not use the excitation signal, rather it uses two different output signal. e.g you have two accelerometers attached to a wind turbine at different location. The transmissibility will tell you how much energy propagate from one point to another. At least this is my current understanding.Chintam (talk) 12:36, 27 March 2019 (UTC)
