EURO-NCAP MPDB Compatibility Impact Model Assessment Using a Virtual Barrier Deformation Tracker
Euro NCAP committee has created the MPDB “Compatibility” test that could change the way we design the vehicle front structure for impact. To assist the crashworthy design development activity for this new mode of impact test, CAE MPDB barrier models have been developed and used by vehicle safety CAE engineers. However, to evaluate the “Standard Deviation” and “Bottom-Out” modifiers accurately from the CAE model run results, a virtual scanner, which can emulate the measurement accuracy of the physical scanner in measuring the depth and size of the deformed MPDB barrier, is required. Currently, the model is built with more than around 350,000 elements and hence the prohibitively large number of elements and nodes need to be tracked to reconstruct the barrier’s deformation contour which is necessary for the “Standard Deviation” and “Bottom-Out” assessment from vehicle-MPDB barrier impact model results.
