Euro NCAP committee has created the Mobile Progressive Deformable Barrier (MPDB) “Compatibility” test that could change the way we design the vehicle front structure for impact [4]. To assist the crashworthy design development activity for this new mode of impact test, CAE barrier models [2] have been developed and used by vehicle safety CAE engineers. These impact models are designed to generate the barrier deformation data essential for evaluation of the scores of the two rating parameters of “Standard Deviation”, “Bottom-Out” for the MPDB impact event. In test, a physical 3-D scanner measures the barrier deformation depth and draws contour plot necessary for determining above two rating parameters. For model results assessment, a virtual scanner, which can emulate the measurement accuracy of the physical scanner is required.
