Rib Deflections 2D (from hardware SBL E)
From the hardware SBL E1 the WorldSID is equipped with the 2D IR-TRACCs, i.e. the deflection and the rotation of the rib is measured. From LS-DYNA WorldSID v5.0 the model offers the 2D IR-TRACCs measurement devices. From LS-DYNA WorldSID v7.0 model 1D IR-TRACCs are available again. LHD and RHD have different discrete elements which are used to measure the deflection and rotation of the Ribs.

For EuroNCAP evaluation the local x- and y-deflections in respect to the spine box are calculated by an equation.
In the simulation model we added different nodes to evaluate the local x- and y-deflections directly from the nodout file for LHD and RHD. The following nodes are defined:
| Item | Node-ID | Label | Available Components |
|---|---|---|---|
| shoulder rib LHD | 10771 | shoulder rib deformation local X/Y/Z | x-, y-, z-displacement |
| 1st thorax rib LHD | 10772 | 1st thorax rib deformation local X/Y/Z | x-, y-, z-displacement |
| 2nd thorax rib LHD | 10773 | 2nd thorax rib deformation local X/Y/Z | x-, y-, z-displacement |
| 3rd thorax rib LHD | 10774 | 3rd thorax rib deformation local X/Y/Z | x-, y-, z-displacement |
| 1st abdomen rib LHD | 10775 | 1st abdomen rib deformation local X/Y/Z | x-, y-, z-displacement |
| 2nd abdomen rib LHD | 10776 | 2nd abdomen rib deformation local X/Y/Z | x-, y-, z-displacement |
| Shoulder rib RHD | 10350 | shoulder rib deformation local X/Y/Z | x-, y-, z-displacement |
| 1st thorax rib RHD | 10351 | 1st thorax rib deformation local X/Y/Z | x-, y-, z-displacement |
| 2nd thorax rib RHD | 10352 | 2nd thorax rib deformation local X/Y/Z | x-, y-, z-displacement |
| 3rd thorax rib RHD | 10353 | 3rd thorax rib deformation local X/Y/Z | x-, y-, z-displacement |
| 1st abdomen rib RHD | 10354 | 1st abdomen rib deformation local X/Y/Z | x-, y-, z-displacement |
| 2nd abdomen rib RHD | 10355 | 2nd abdomen rib deformation local X/Y/Z |
x-, y-, z-displacement |
The results of these nodes should give the same output as calculating the local deflections from the resultant deflections and rotation of 2D IR-TRACCs.
