BISOPE series 63- Graphs related to
amplitude and frequency ---------------------------------------------------------------------------
There
is an object that changes its position and repeatedly moves back and forth
around a certain standard. On the other hand, there are objects that end with a
single push or pull. Which one takes more strength? If you look closely at the
fitness equipment nearby in your daily life, you will see that what you moved
with effort must be returned to its original position before you can apply
force in the same direction in the next exercise. In fact, which force is
applied is not that important when comparing two movements. However, the key is
how much greater force is applied and how often. We understand that all
physical waves appear as noise in the air and as vibration (repetition) in
objects. And if you draw it as a two-dimensional graph, it can be expressed
directly as the X and Y axes. This is ‘change in size over time’.
X and Y axes of vibration
The X~~~
Y axis |
Main unit |
Displacement (µm, mm), velocity (mm/s,
cm/s), acceleration (m/s², G) |
Sub
unit |
0-peak, peak to peak, rms |
The ‘Z’ axis (third axis)
can be used to express the amplitude of vibration, and it mainly plays the role
of RPM in Campbell, Waterfall, etc.
