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.
