<b>Abstract</b>:

|
Tighter specifications in synchrotron instrumentation development force the design engineers more and more often to choose a mechatronics design approach.
|
||
|
|
This includes actively controlled systems that need to be properly designed.
|
||
|
|
The new Nano Active Stabilization System (NASS) for the ESRF beamline ID31 was designed with such an approach.
|
||
|
|
</p>
|
||
|
|
|
||
|
|
<p>
|
||
|
|
We chose a multi-body design modelling approach for the development of the NASS end-station.
|
||
|
|
Significance of such models depend strongly on its input and consideration of the right stiffness of the system’s components and subsystems.
|
||
|
|
For that matter, we considered sub-components in the multi-body model as <i>reduced order flexible bodies</i> representing the component’s modal behaviour with reduced mass and stiffness matrices obtained from finite element analysis (FEA) models.
|
||
|
|
These matrices were created from FEA models via modal reduction techniques, more specifically the component mode synthesis (CMS).
|
||
|
|
This makes this design approach a combined multibody-FEA technique.
|
||
|
|
</p>
|
||
|
|
|
||
|
|
<p>
|
||
|
|
We validated the technique with a test bench that confirmed the good modelling capabilities using reduced order flexible body models obtained from FEA for an amplified piezoelectric actuator (APA).
