Euro NCAP Virtual Far Side VC2 (Assessment Criteria)
This topic focuses on the automation of the Validation Criterion 2 (Assessment Criteria) assessment using REPORTER. You can also use Automotive Assessments to perform the correlation interactively.
Introduction
The Euro NCAP Virtual Far Side 2024 VC2 (Assessment Criteria) REPORTER Template can be used to perform the Validation Criterion 2 (Assessment Criteria) check according to section 6.3.10 of the Euro NCAP VTC Simulation and Assessment Protocol v1.0:
Validation Criterion 2 (Assessment Criteria): \(d_{AC} < 30\%\)
If the template is successfully generated it will show a report summarising the assessment criterion limits, values, \(r_{AC_{sim}}\), \(r_{AC_{test}}\) and \(d_{AC}\) as well as Far Side scores. The graphs for all the assessment data and structures are plotted to allow you to understand the results in more detail.
Firstly, in PRIMER, you should have set up the occupant and structures required for your Simulation model. This can be found in Workflows in the tools menu, then Automotive Assessments and under the Crash Test dropdown find 'Far Side + VTC' and fill out the Driver and Structures (Airbag is optional). Then save the created Workflows data using the Save to File or Save to Model buttons. For more information see the 'Automotive Assessments PRIMER' manual.
Using the REPORTER template
Before using the REPORTER template, you should have defined the occupant and structures user data required for your model in PRIMER (see Automotive Assessments PRIMER for details).
In REPORTER, click the tab and then filter by Virtual Testing (under protection) & Euro NCAP (under regulation) and double-click to open the template.
You will first be prompted to select your Test file, this can be .iso, .mme, .chn or .csv format:
Next you will be prompted for the distance between the Head CoG and the Red Line which marks the inboard intrusion from your previous Side MDB or Side Pole simulation.
Finally you will be prompted for the Simulation (.key) file. Once selected the REPORTER Template will run and produce the results.
REPORTER Results
Page 1 contains the DRIVER_HEAD_EXCURSION, and all the required assessment data (Values, Far Side Scores, Assessment Criteria Limits, \(r_{AC_{sim}}\), \(r_{AC_{test}}\) and \(d_{AC}\) values). The total Validation Criterion 2 pass or fail is then displayed next to the Far Side Assessment Criteria scores out of 12.
Page 2 contains more in depth results for the Simulation Model and Page 3 contains the same set of results for the Test Model.
Pages 4 to 10 display the graphs for the required assessment data and pages 11 to 24 display the structure data from Table 6 in the Euro NCAP VTC protocol.
Running in Batch
The template can also be run in batch mode, specifying the required information through command line arguments.
If your results are in the same directory as the keyword file then you only need to specify the keyword file on the command line and the test file and red zone which are specific to this template:
<reporter_exe> -batch -file=<template_name> -varKEYWORD_FILE=<keyword_file> -varTEST_FILE=<test_file> -varRED_ZONE=<red_zone> -exit
[Add the -pdf, -html, -pptx command line arguments to write the report out in the format you want]
Where:
| reporter_exe | The full path and filename to the REPORTER executable |
|---|---|
| template_name | The full path and filename of the template you want to use. The workflow templates can be found in $OA_INSTALL/workflows/templates/automotive_assessments |
| keyword_file | The full path and filename of the keyword file |
| test_file | The full path to the ISO-MME or CSV file to be used for the Test model |
| red_zone | Distance between the Head CoG and the Red Line |
If the results are in a different folder to the keyword file, you will need to add an extra argument to specify it:
<reporter_exe> -batch -file=<template_name> -varKEYWORD_FILE=<keyword_file> -varTEST_FILE=<test_file> -varRED_ZONE=<red_zone> -varRESULTS_DIR=<results_dir> -exit
Where:
| results_dir | The full path to the results directory |
|---|
Similarly if you want to output the images and other files generated by REPORTER to a different folder than the default, you will need to add an extra argument:
<reporter_exe> -batch -file=<template_name> -varKEYWORD_FILE=<keyword_file> -varTEST_FILE=<test_file> -varRED_ZONE=<red_zone> -varOUTPUT_DIR=<output_dir> -exit
Where:
| output_dir | The full path to the output directory |
|---|
