* Experimental conditions
- Measurement made in a metrology lab
- The granite is not glued to the floor
- The Y-Translation stage is powered and in closed-loop
- The spindle is not powered
- Mass is placed on top of the Hexapod (*how much?*) (figure [[fig:accelerometers]]).
- Made by Marc Lesourd on the 17th of November 2017

* Measurements procedure
*3-axis Accelerometers* (specifications table [[tab:accelerometer]]) are glued on (see figure [[fig:accelerometers]]):
- Marble
- Y-Translation stage
- Tilt stage
- top of Hexapod
#+NAME: tab:accelerometer
#+CAPTION: Pieozoelectric acc. 356b18 - 3 axis
| Sensitivity | 0.102 V/(m/s2) |
| Measurement Range | 4.9 m/s2 pk |
| Frequency Range | 0.5 to 3000 Hz |
| resonant frequency | >20000 Hz |
| broadband resolution | 0.0005 m/s2 rms |
The structure is excited using an *instrumented hammer* with impacts on (see figure [[fig:instrumented_hammer]]):
- Marble
- Hexapod
* Measurement Files
Two measurements files are:
- =id31_microstation_2017_11_17_frf.mat= that contains:
- =freq_frf= the frequency vector in Hz
- Computed frequency response functions (see table [[tab:data_name]])
- =id31_microstation_2017_11_17_coh.mat=
- Computed coherence
For each of the measurement, the measured channels are shown on table [[tab:meas_channels]].
