ECCENTRIC MASS VIBRATORS - ANCO Engineers

Eccentric mass vibrators use one or more rotating eccentric weights to produce a force which increases in direct proportion to the eccentricity and to the square of the rotating frequency. The force produced is thus given by the relationship: F (lbs) = 0.102 X WR X f x f where WR is the eccentricity in lb-inches and f is the frequency in Hz.
