The goal is to experimentally extract a <b>Spatial Model</b> (mass, damping, stiffness) of the structure (shown on figure <a href="#orgf65e30f">1</a>) in order to tune the Multi-Body model.
</p>
<div id="orgf65e30f" class="figure">

</div>
<p>
The procedure is represented on figure <a href="#org28538ba">2</a> where we go from left to right.
</p>
<div id="org28538ba" class="figure">

</p>
<p><span class="figure-number">Figure 2: </span>Vibration Analysis Procedure</p>
</div>
<p>
The steps are:
</p>
<ul class="org-ul">
<li>we obtain a <b>Response Model</b> (Frequency Response Functions) from measurements (described <a href="measurement.html">here</a>)</li>
<li>the response model is further converted into a <b>Modal Model</b> (Natural Frequencies and Mode Shapes) (described <a href="modal_extraction.html">here</a>)</li>
<li>this is converted into a <b>Spatial Model</b> with the Mass/Damping/Stiffness matrices (described <a href="mathematical_model.html">here</a>)</li>
</ul>
<p>
Theses matrices will be used to tune the Simscape (multi-body) model.
</p>
<p>
The modes we want to identify are those in the frequency range between 0Hz and 150Hz.
</p>
<p>
The modal analysis of the ID31 Micro-station thus consists of several parts:
