The goal here is to make an identification of the < b > micro-station< / b > in order to compare the model with the measurements on the real micro-station.
2019-10-08 11:13:38 +02:00
< / p >
< p >
In order to do so:
< / p >
< ul class = "org-ul" >
< li > Decide where to virtually excite the station and where to measure its motion< / li >
< li > Extract transfer functions from the excitation forces to the measured motion< / li >
< li > Compare those transfer functions with the modal analysis< / li >
< / ul >
< p >
For the excitation, we can choose the same excitation points as the one used for the modal test.
For the measurement points, we can choose the Center of Mass of each solid body.
The center of mass of each solid body is not easily defined using Simscape.
Indeed, we can define the center of mass of any solid body but not of multiple solid bodies. However, one solid body is composed of multiple STEP files.
One solution could be to use one STEP file for one solid body.
However, the position of the center of mass can be exported using simulink and then defined on Simscape.

We first define some parameters for the identification.
The simulink file for the identification is < code > sim_micro_station_id.slx< / code > .
