Introduction

This document supports the Virtual Testing – Crashworthiness Far side Assessment Protocol
by providing details of the data required in qualification of WorldSID CAE models. From 2024
onwards VTC simulation data will be required for all vehicles assessed by Euro NCAP.
The WorldSID AM50 model qualification process is divided into three stages beginning withnormative standard requirements, component test simulations and full scale far side sled test
simulations performed in a simplified environment. In addition to this document, it is also
necessary to refer to the Standard ISO 15830, the Euro NCAP VTC Simulation and Assessment
Protocol as well as Euro NCAP Technical Bulletin TB 021. Additional reference documents
and additional information are available using the following links:
Euro NCAP | Protocols
https://openvt.eu/EuroNCAP/wsid-model-qualification
In future, additional sizes of WorldSID model will be incorporated into the VTC assessment
and this document will also be updated accordingly.

•
•

Normative references
The model evaluation is based on the following normative references:
Mass properties according to ISO 15830-2 & -5
External dimensions according to ISO 15830-5
Range of motion according to ISO 15830-1
Sensors according to ISO 15830-3
Dummy dynamic qualification procedures according to ISO 15830-2

2.1.2 The ISO 15830 is currently under revision, therefore the referenced documents are
given undated and the latest version of the ISO document shall be used.
2.2
Simulation Setup
2.2.1 All qualification procedures described in the ISO 15830-2 must be simulated with theWorldSID AM50 model. All setups must also meet the following simulation-related
requirements:• Dummy-related control cards must match in all three stages• Active gravity• Signals must be outputted and filtered according to the specification in the ISO 158302
2.2.2 The last specification requires an output of signals before t0 to perform filtering andoffset correction as requested in the norm, this is why the simulation must start withsome time in advance of t0.

Stage 2 – Component Level Tests

3.1
Dummy model suitability – sub-system simulation
In Stage 2, the application-specific suitability of the dummy model is checked at component
level via mini-sled tests. The first test setup is used to validate the model’s head-neck
performance whereas the second setup focuses on the lumbar spine performance. In both
setups, lateral and oblique load cases are included. The same acceleration pulse is used in all
the four load cases, which is shown in Figure 1.

Stage 3 – Full Scale Tests
4.1
Dummy model suitability – full assembly simulation
In stage 3, the models’ application-specific suitability is checked at a full assembly level using
two sled tests. Both tests are based on the same generic environment with a 75° oblique
direction pulse, see Figure 4. However, in the first test, target delta v = 8 m/s (slow), whereas
in the second sled test target delta v = 11 m/s (fast).

Figure 4: Acceleration profile for v = 11 m/s (left) and v = 8 m/s (right)
4.2
Reference signals
Data for the two sled tests were generated under the following projects:••

For Δv = 8 m/s, data was generated within experiments performed in the OSCCAR
project (funded under EU Horizon 2020 research and innovation programme, under
grant agreement No. 768947)
For Δv = 11 m/s, data was generated using CEESAR-LAB test data (Petit. et al., 2019)

4.3
Reference Data
The following finite element reference models and reference data sets are needed for thisprocedure:
4.3.1 Reference CAE data: mesh for sled environment, boundary conditions restraint settings
and target position reference for model’s posture alignment for sled test with Δv = 8m/s• 11_reference_meshes/Far side_8mps/master_8mps.key
4.3.2 Reference CAE data: mesh for sled environment, boundary conditions, restraint settings
and target position reference for model’s posture alignment for sled test with Δv = 11m/s

4.4
Simulation setup
4.4.1 Environment
4.4.1.1 The sled test setup consists of separated components assembled in a common rigid
frame as shown in Figure 5 & Figure 6. Apart of the rigid frame, the setup includes arigid inclined seat pan, a rigid frame with two horizontal bars as seatback, rigid
footrest, two centre consoles (one for legs and one for pelvis), 3-point belt, retractor,
and belt attachment points.
Note: The test setup is provided in a left-handed drive car seat configuration.
4.4.1.2 The dummy model is seated on a rigid seat pan mounted on a rigid frame through loadtransducers. The model’s feet rest on a rigid support, which is mounted on a rigid
frame. The rigid frame is fixed onto the catapult sled system. The rigid consoles arecovered with 50 mm thick Polyethylene foam (Ethafoam TM 180, density 16 kg/m³).
The 3-point belt is not connected to the seat (left-hand drive car seat), but to the rigid
frame though attachment points. A preload in the shoulder belt was applied andmaintained at a force of 200 N.
4.4.1.3 The following contacts shall be defied with coefficients of friction between 0.10-0.60:• WorldSID-seat• WorldSID-seatbelt• WorldSID-centre console
All contacts shall be checked to work properly (no large penetrations or sticky nodes).
The applied contact settings (type and friction coefficient) must be reported in the qualification
documentation report.

4.4.2 Dummy Model Preparation
4.4.2.1 The dummy model is seated, targeting the hip point, head centre point and surface
data of the WorldSID in the physical test position. The target postures for the two sledtests are provided in reference CAE data files.
4.4.2.2 Due to the seat’s flat shape, the model’s deformation at the bottom shall be considered
to avoid initial penetration between model’s bottom and seat plate when the model isseated.
4.4.2.3 It is noted that the target posture of the WorldSID provided for the CEESAR
environment (sled test with Δv = 11 m/s) was not straight but leaning slightly to thedummy’s left side. This is intentional to simulate the laboratory setup as close as
possible. The described leaning posture is not present in OSCCAR target postureprovided (sled test with Δv = 8 m/s).
4.4.2.4 The belt path shall be as close as possible to the provided reference belt path in thereference CAE file and adapted to the dummy's achieved body position.
4.4.2.5 Contact definitions between model and the generic environment are pre-defined andprovided together with the target posture in the reference CAE file.
4.4.3 Loading and other configurations
The following conditions must be considered:••••

The sled must be loaded with pulses matching the provided reference signal data. The
loading applied as ‘velocity-time’ boundary prescribed motion is provided in reference
CAE data files.
The simulation must be performed with active gravity.
Dummy model-related control cards must match in all three stages.
End time ≥ 200 ms.

5.1.5.1 Filter all channels with CFC60 according to SAE J211 or ISO 6487
5.1.5.2 Apply ‘bias removal’ of all channels between t = 5 ms and t = 10 ms by calculating
the mean value of the given interval and offsetting the signal by the mean value (seeFigure 7 below)

Figure 7: Channel bias removal
The test data has already been prepared, so that it can be directly used for the calculation of the
ISO scores. In addition to filtering with CFC60, ‘bias removal’ was applied for all channels
between t = 5 ms and t = 10 ms.

5.1.6 Calculation of scores
The overall evaluation is composed of several scores, which are calculated sequentially one
after another.
5.1.6.1 Channel score
The score of a channel must be calculated for a specific interval by application of the ISO
metric as specified in ISO/TS 18571. The interval of evaluation for each load case is listed inTable 7. All necessary channels are listed in Table 2, Table 5 and Table 6. The provided
reference data must be used as reference curves, whereas the simulation data must be used as
evaluated curves.

5.1.6.2 Sensor score
The sensor score is calculated by summarising all three weighted channel scores per sensor
according to Equation 1. All weighting factors per channel, sensor and load case are listed inTable 13, Table 14 and Table 15.

Additional Information on the Development of WorldSID Model Qualification
This Section describes how the reference data was generated.
8.1
Test curve processing
The following general procedure was used in all case to generate the reference data out of thetest data sets.
8.1.1 Identify the reference channel(s), see Table 11.
8.1.2 If multiple reference channels are listed, create average of reference channels and use
average as reference channel.
8.1.3 Filter all channels with CFC60.
8.1.4 Identify the starting time of reference channel (t0 preliminary).
8.1.5 Apply bias removal of reference channel between t0 preliminary = -50 ms and t0
preliminary = -10 ms.
8.1.6 Time zero t0 is defined as the time when the first data sample of the reference channel
exceeds the search level, see Table 11.
8.1.7 Apply a test specific final time shift to all measured channels, see Table 11.
8.1.8 Apply a test specific bias removal of all signals except the reference channel, IRTRACC angle and length, see Table 11.
8.1.9 Calculate the mean of all test repetitions for each signal excluding failed channels listed
in Table 12.

The reference data set includes only channels needed in the dummy model certification process.
The sled pulses are modified in such a way, that a(t0) = 0 m/s².

8.2
Values for determination of weighting factors
8.2.1 The following tables list the absolute maximum value of each channel per test for the
calculation of the weighting factor according to Equation 5:
Equation 5
𝑤𝑖 =max(|𝐶ℎ𝑎𝑛𝑛𝑒𝑙𝑡𝑒𝑠𝑡 𝑖 |)max(|𝐶ℎ𝑎𝑛𝑛𝑒𝑙𝑡𝑒𝑠𝑡 𝑥 |) max (|𝐶ℎ𝑎𝑛𝑛𝑒𝑙𝑡𝑒𝑠𝑡 𝑦 |) + max(|𝐶ℎ𝑎𝑛𝑛𝑒𝑙𝑡𝑒𝑠𝑡 𝑧 |)𝑤𝑖𝑡ℎ 𝑖 = 𝑋, 𝑌, 𝑍

with max(|𝐶ℎ𝑎𝑛𝑛𝑒𝑙𝑡𝑒𝑠𝑡 𝑖 |) maximum absolute value of the channel in the respective axis
direction.
8.2.2 If the summed weighting factors of a signal are not equal to 1.0000, the lowest
weighting factor is modified accordingly.
