Euro NCAP Virtual Far Side VC1 (ISO Scores)
This topic focuses on the automation of the Validation Criterion 1 (ISO Scores) assessment using REPORTER. You can also use SimVT to perform the correlation interactively.
Introduction
The Euro NCAP Virtual Far Side 2024 VC1 (ISO Scores) REPORTER Template can be used to perform the Validation Criterion 1 (ISO Scores) check according to section 6.3.5 of the Euro NCAP VTC Simulation and Assessment Protocol v1.0:
Validation Criterion 1 (ISO Scores): \(S_{Sensor} > 0.5\)
If the template is successfully generated it will show a report summarising the the sensor scores for all the mandatory and monitored channels (listed in Table 6 of the protocol) as well as the correlation graphs for each channel so that you can inspect any channels which perform poorly. Additionally, a SimVT settings file (REPORTER_settings.simvt) is created which can be loaded in to the SimVT workflow tool to interrogate the results interactively.
Before using the REPORTER template with Ansys LS-DYNA data you should have defined the occupant and structures user data required for your model in PRIMER (see Automotive Assessments PRIMER for details).
The REPORTER Template can be run interactively or in batch mode to generate the REPORT and the instructions for running SimVT REPORTER Templates can be found here.
Report Pages
Page 1 contains a summary of the results for all the assessed and monitored channels. It shows the PASS/FAIL status of Validation Criterion 1 as well as the run duration PASS/FAIL status that requires the simulation time to be greater than 1.2 times the time of maximum head excursion.
Page 2 shows the trace of simulation head excursion versus time. The trace must extend in to the green zone in order for the check to pass.
Pages 3-25 show the corridor plots for each sensor. 3D sensors will have X, Y and Z plots:
1D Sensors will have a single plot:
Monitored sensors are shown with the PASS/FAIL status in parenthesis (e.g. "(PASS)" in the image above means that the seatbelt B3 force sensor passed the check, but the Euro NCAP protocol only requires it for monitoring purposes at the moment).
The final pages of the report contain a table showing the detailed results for each correlation so that they can all be viewed in one place.
