For EuroNCAP evaluation the local x- and y- deflections in respect to the spine box is calculated by an equation.
In simulation model we have added different nodes to evaluate the local x- and y- deflections directly form the nodout file for LHD and RHD. Nodes are defined:

In the WorldSID model from version 7.0, the measurement of the length and relative rotation of IR-TRACCs are available for both side (LHD and RHD).

  • In the WorldSID model from version 7.0, the measurement of the pelvis force are available for both sides (LHD and RHD). Pelvis bone is separated into small parts for evaluations through *CONTACT_FORCE_TRANSDUCER_PENALTY_ID.
