The rms value V _f of the vibration velocity is the reference quantity for rotating machines with a frequency of rotation between 10 and 200 s ^-1 (NF E 90-300, May 1978). Measurements of V _f carried out on machine bearing caps are planned within the limits 0.28 < V _f (mm.s ^-1 ) < 45 and for frequencies 10 < f (Hz) < 1,000.

The equivalent acceleration a _eq ...
