Representing the force and vibration in the frequency .... if the associated
vibrations are measured, the frequency ...
Before taking a vibration measurement, you need to attach a sensor that can ....
operating speed of the machine, the higher its frequencies of vibration will be, ...
Vibration measurement is complex because of its many components –
displacement, velocity, acceleration, and frequencies. Also, each of these
just like the machines from which the vibration is measured. ... Acceleration
increases relative amplitude with increasing frequency and is therefore the
Mar 26, 2013 ... This sort of thing is my day job! There are lots of variations depending on the sort
of ... First, the natural frequency of an object is not unique.
The devices have very low natural frequencies and are designed to measure
vibration frequencies that are greater than the natural frequency of the pickup.
Feb 25, 2013 ... Measuring Vibrations in GThose looking for the Quick Vibe Estimator ... simply
the object being repeatedly displaced and a very high frequency.
Sep 5, 2011 ... Some use strain gauges, but many others use a capacitive effect or induced radio
frequency mechanism to measure displacement directly.
Often, small insignificant vibrations can excite the resonant frequencies of some
other structural parts and be amplified into major vibration and noise sources.
Feb 1, 1999 ... Some of the earliest "high-frequency" vibration measurements were made with
electrodynamic velocity sensors. These are a type of seismic ...
