so that the frequency ratio approaches infinity. The
net Wr, on the resultant axis, of the rotating unbalance
system equals the Wx of the vibrating body containing
the unbalances; there is no magnification, and amplitude
is, therefore, constant at all frequencies in its
operating range, as shown in Fig. 6.
Amplitude is also unaffected by the amount of, or
variances in, material loading, because the motion, confined
to the plane of the conveying surface, doesn't lift
the load. Neither is amplitude affected by material
damping characteristics.
Amplitude is affected by any attached masses, such
as material deposits, that may be added to the bare
weight, but only in direct proportion to the weight
increment.
