Finite Element Model of the Support Bridge
The global description of the OT Station design can be found in the
Introduction .
To optimize the design of the
Support Bridge ,
a Finite Element Models (FEM) was employed.
In the FEM, a set of loads is applied as shown in the
table below ,
in order to study the displacements of the Support Bridge:
-
OT/IT in the nominal position
(Load Set 1)
-
OT slid out
(Load Set 2)
-
Worst-case scenario with full load in the center, e.g. during detector
installation
(Load Set 3)
-
Only "long" OT half slid out
(Load Set 4)
Load sets: OT in position (top left); OT slid out (top right);
full load in the center (bottom left); half OT slid out (bottom right).

The 3D displacements calculated in the
FEMs shown above as a result of applying these
load sets are shown in the
pictures below.
3D displacements under four load sets in the FEM.
