Dual Occupant Penalties
Dual Occupant Penalties
This guide helps users to set up and perform the occupant injury assessments for the Far Side Protocol Dual Occupant Scenario Penalties for the Passenger and Driver for the WSID and ES-2re dummies as specified in section 1.2.1.5.4 of the C-NCAP Management Regulation (2024).
Please note this guide runs through using the CNCAP Far Side Protocol 2024 Dual-Occupant Penalty (WSID Passenger) template, but this guide still applies for WSID Driver, ES-2re Passenger and ES-2re Driver templates.
The dual-occupant side pole impact scenario calculates two penalties to be deducted from the overall Far Side Protocol score. The passenger penalty is required and contributes towards a maximum 1.5 penalty points. The driver airbag symmetry penalty is required if centre console airbags are present and contributes towards a maximum 0.5 penalty points, you must pass the C-NCAP Far Side Protocol 2024 Virtual Assessment Certificate otherwise the driver airbag symmetry penalty will be automatically set to 0.5.
Set-up using Automotive Assessments in PRIMER
Firstly, you need to attach Workflows Automotive Assessments data to your model(s). Follow this guide to see more: Automotive Assessments in PRIMER.
- For WSID Passenger, for Crash Test select Side Pole, for Regulation select CNCAP, for version select 2024 (WSID+WSID)
- For WSID Driver, for Crash Test select Far Side Pole, for Regulation select CNCAP, for version select 2024 (WSID+WSID)
- For ES-2re Passenger, for Crash Test select Side Pole, for Regulation select CNCAP, for version select 2024 (WSID+ES-2re)
- For ES-2re Driver, for Crash Test select Far Side Pole, for Regulation select CNCAP, for version select 2024 (ES-2re+WSID)
Running the templates in REPORTER
In REPORTER there are four related templates, to find them go to the Automotive tab and filter by 'Virtual testing' under Protection and 'C-NCAP' under Regulation.
- C-NCAP Far Side Protocol 2024 Dual-Occupant Penalty (WSID Passenger)
- C-NCAP Far Side Protocol 2024 Dual-Occupant Penalty (WSID Driver)
- C-NCAP Far Side Protocol 2024 Dual-Occupant Penalty (ES-2re Passenger)
- C-NCAP Far Side Protocol 2024 Dual-Occupant Penalty (ES-2re Driver)
Upon opening the templates you will be asked a series of questions:
Firstly, select your Ansys LS-DYNA (.key) keyword file
Then you will then be asked whether you want to continue with the default results and output directories or configure them in PRIMER
REPORTER Results
Page 1 contains the limits, values and results (pass or fail) for each assessed body region, an explaination of the penalties and the total penalty score.
Pages 2 and beyond display the injury graphs.
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> -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 |
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> -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> -varOUTPUT_DIR=<output_dir> -exit
Where:
| output_dir | The full path to the output directory |
|---|
