1. Introduction
In the late 1970s and early 1980s, TNO and others developed the P-dummies, a series of
child dummies that covers almost the complete child population up to 12 years. The P-
series dummies are still test tools for the European regulation ECE-R44 and are also
adopted by many other standards.
In 1993 the International Child Dummy Working Group started the development of a new
series of child dummies as a successor to the P-series. This new series was called the Q-
series. Part of the development and evaluation of the Q-dummies took place within
European Research programs like CREST
1
, CHILD
2
, CASPER
3
and EPOCh
4
all aiming at
improving child safety in cars. As of December 2011 the series is available in five age
groups, representing a Newborn, 1 year, 1½ year, 3 year, 6 year and 10 year old child.
Nowadays members of this Q family are applied in UNECE Regulation R129 which became
effective per January 2013. Also various consumer rating programs world-wide apply Q
dummies.
Humanetics reserves the right to make improvements or implement changes to the
dummy, the certification or the user manual if this is deemed necessary. We will of course
inform our customers of any changes or modifications should they occur.

2. General Description and Features
2.1 Design History
The development of the Q-series, directed by the International Child Dummy Working
Group, resulted in a Q3 dummy in 1998, followed by the addition of the Q6 dummy in
1999, and the Q1 in 2000.
Based on customer feedback and test results, Humanetics has received comments on the
dummies’ performance and durability. This has resulted in an update program that was
started in 2004. This update was aimed at a number of issues with the Q dummies in the
shoulder, and head/neck area. During this period the Q0 and Q1.5 were added to the
family, based on Q-series anthropometry and biofidelity data.
The European Enhanced Vehicle-safety Committee performed an extensive evaluation
program of the Q-series in 2004. A full report on a possible recommendation for use of
the dummies in ECE R44 tests is expected in 2005. Results of the first evaluations have
been published at the 19th Enhanced Safety of Vehicles conference in 2005
5
. In 2006 the
New Programme for the Assessment of Child-restraint Systems (NPACS) adopted the Q
dummies for their test protocols.
2.2 Application
The Q3 dummy is suitable for frontal as well as side impact CRS evaluations, to be used
for both homologation, consumer rating and research purposes. Applications include:
Child Restraint Systems (CRS) type approval testing. This includes the UNECE
Regulation R129 in which the Q3 dummy is applied from January 2013 on to assess
integral Child Restraint Systems (CRS). From July 2017 on the Q3 dummy will be used
to assess non-integral CRS as well.
Consumer rating tests. The dummy has been designed to withstand impact with
closing velocities up to an average Euro NCAP level. From January 2013 till December
2015 the Q3 was used in the Euro NCAP protocols together with the Q1.5. These have
now been replaced by the larger Q10 and Q6 respectively. However, other NCAP

organizations like Latin NCAP and in the future also Indian NCAP remain or start using
the Q3 dummy.
The European Test Consortium (ETC) for Child Restrain Seats uses the Q series for their
frontal and side impact consumer test procedures for CRS performance rating
6
.
Out-of-position tests (OOP), including airbag interaction.
2.3 Features
The Q-dummies have improved biofidelity over the P-series. Biomechanical
information from children and scaled adult biomechanical response curves has been
used to define the dummy response. The anthropometry of the dummy is based on
CANDAT data.
The dummies can be equipped with accelerometers, angular velocity sensors, load cells
and displacement sensors. This allows evaluation of the injury risk under various
circumstances.
Special attention has been paid to the handling characteristics of the dummy, ensuring
the dummy can be assembled and disassembled quickly, and installing the dummy in
the test configuration is simple and repeatable.
The influence of transducers upon the kinematics of the dummy is minimized, and
protection of transducers and cables is integrated in the dummy design.
Head
The head is largely made from synthetics. The head cavity is large enough to allow use
of several instruments, including linear accelerometers and angular velocity sensors.
Neck
The neck is flexible and allows shear and bending in all directions. The segmented design
allows a realistic rotational behavior. The neck is equipped with low stretch neck-cord in
order to prevent excessive elongation. The neck-cord is also designed to act as a safety
cord in case of rubber failure. A six channel load cell can be mounted at the neck-head
and neck-torso interface.

Thorax
The thorax of the child is represented by a single rib-cage. The deformation can be
measured with an IR-TRACC sensor. The shoulders are connected with a flexible joint to
the thorax, allowing deformation forwards. Accelerometers can be mounted on the
spine to measure linear accelerations.
Abdomen
The abdomen is foam covered with skin. Biomechanical data from children has been used
to determine the required stiffness.
Lumbar Spine
The lumbar spine is a flexible rubber column, which allows shear and bending in all
directions. A six channel load cell can be mounted between the lumbar spine and the
pelvis.
Pelvis
The Q-dummy pelvis has removable hip joints. An accelerometer array can be mounted
in the pelvis. Special hip joints are available that allow to position the dummy in a standing
position.
Legs
The knee joints can be locked in any position. This feature can be used to facilitate
positioning the dummy in a standing position. Note that the dummy does not have the
ability to stand without support. It must be placed against some object, such as the
dashboard.

3. Instrumentation
3.1 General
The dummy accepts both accelerometers and load cells as standard instrumentation.
Angular velocity sensors (DTS-ARS and Applied Technologies Associates type ARS-01 or
ARS-06 (flanged version)) can be fitted to the head; this requires an alternative head
accelerometer mount. The dummy can be equipped with uni-axial accelerometers for all
locations. Tri-axial accelerometers can be used on the pelvis and thorax location. The
standard dummy will be delivered including mounting blocks for uni-axial
accelerometers.
The load cells or its structural replacements are a part of the dummy structure; the
structural replacements have to be used in absence of the actual transducer. A 6-channel
load cell (Humanetics model IF-217 or IF-218) can be placed in the upper neck, lower
neck and lumbar spine location.
3.2 Transducers
The Q3 dummy can be fitted to measure any or all of the following parameters (see also
notes below):
Head
Standard - 3 uni-axial accelerometers in head (Ax, Ay, Az)
Optional - 3 angular velocity sensors:
Applied Technologies Associates type ARS-01 or ARS-06 (flanged version)
or DTS-ARS.
Neck
Standard - Upper neck 6 channel load cell, 3 forces, 3 moments (Fx, Fy, Fz, Mx, My,
Mz). Humanetics Model IF-217 (350 Ohm) or IF-218 (120 Ohm).
- Lower neck 6 channel load cell, 3 forces, 3 moments (Fx, Fy, Fz, Mx, My,
Mz). Humanetics Model IF-217 (350 Ohm) or IF-218 (120 Ohm).
Thorax
Standard - 3 uni-axial accelerometers (or tri-axial accelerometer) in upper spine (Ax,
Ay, Az).
- 1 IR-TRACC sensor to measure chest deformation, frontal or lateral (Dx or
Dy). Humanetics model IF-362.
Optional - Additional accelerometers may be installed with double sided tape on the
thoracic spine (Ax, Ay) (see notes below).

020-9905 User Manual Q3 (Advanced 3 year old child) Rev G Page 14 of 82
© 2016 Humanetics Innovative Solutions
Lumbar Spine
Standard - 6 channel load cell at lumbar spine/ pelvis interface (Fx, Fy, Fz, Mx, My,
Mz). Humanetics Model IF-217 (350 Ohm) or IF-218 (120 Ohm).
Abdomen
Optional - Abdomen Pressure Twin Sensors (APTS)
Pelvis
Standard - 3 uni-axial accelerometers (or tri-axial accelerometer) on pelvis skeletal
structure (Ax, Ay, Az).
Notes:
1. IR-TRACC sensor may be mounted in two ways, either to measure frontal or lateral
deformations. The IR-TRACC sensor cannot record the true deformation in oblique
impacts. It is recommended not be use the IR-TRACC in tests with expected high oblique
rib deformations; this can cause damage to the IR-TRACC sensor, as it has limited range
of motion in directions perpendicular to its sensitive deflection direction.
2. Information on the installation of the instrumentation can be found in the
assembly/disassembly section of this manual.
3. The Upper Neck Load Cell does not require any correction for measurement of the
moment around the OC joint. The (theoretical) OC joint coincides with the neutral axis of
the moment measurement of the (Humanetics) load cell.
4. Additional accelerometers may be mounted in the dummy for extra/redundant
information. There are no fixed points for attaching these accelerometers. Instead,
double-sided tape may be used to attach the accelerometer to the desired location. Two
accelerometers may be used to measure deformation velocity and the deformation itself.
The procedure is as follows:
Install the accelerometers in the dummy. The sensitive axes of the transducers should be
aligned as good as possible. Furthermore, the accelerometers should be installed in
locations that are expected to retain their alignment during the deformation phase. Make
sure that the accelerometers are not located on positions that may contact other parts of
the dummy as a result of deformation. To process and combine the data first filter both
signals at CFC1000 according to SAE J211. Subtract the signals and integrate the result.
This results in the deformation velocity. Numerical integration of this signal gives the
deformation itself.

020-9905 User Manual Q3 (Advanced 3 year old child) Rev G Page 15 of 82
© 2016 Humanetics Innovative Solutions
Note that this method gives an approximation of the actual deformation. The accuracy is
limited due to the fact that the accelerometers do not remain properly aligned during the
test and the numerical integrations that include the small measurement errors of the
accelerometers cumulative in the velocity and displacement result. The longer the time
interval is the larger the cumulative error can be. Experience with the Q3 dummy shows
that usage of the acceleration integration method results in an under-estimation of the
deformation. At 4.3 m/s initial impact velocity the refv is approximately 10%. At 6.7 m/s
it is approximately 20%.
3.3 Accelerometer Mounts
Humanetics support three brands/models of accelerometers or equivalent
Endevco 7264 and 7267A series
Entran EGAS Series and EGE3-73 Tri-axial.
Kyowa ASM Series
MSC 126M/CM Uni-axial accelerometers
The uni-axial accelerometers and mounts that can be used for the Q3 dummy are listed
Table 3. The mounts and their orientation are depicted in figure 2 to 5. Tri-axial
accelerometers and mounts are listed in Table 4.
Note: The tri-axial accelerometers Endevco 7267A and Entran EGE3-073 cannot
be fitted to the head. The head will only accept uni-axial accelerometers.
Note: Thorax and Pelvis locations will ONLY accept tri-axial transducers with a
side-entry cable.

3.4 Angular Velocity Sensor Mounting
The application of angular velocity sensors is possible in the head. There are two
options:
1. ATA ARS-01 or ARS-06 (flanged version) (see Figure 6) with special mount block
020-1014. The mount block 020-1014 consists of a base and three ATA ARS
sensor blanks of similar weight and size. Any of these ARS sensor blanks can be
replaced with an ATA ARS-01 or ARS-06 (flanged version) sensor. The 020-2014
mounting block will accept the same mount block as the standard accelerometer
mounting for the head (I.AD or I.AM, see Figure 2). The ATA ARS sensor blanks
should not be removed if there are no sensors to replace them.
Figure 6. ATA ARS-01 (left) and ARS-06 (flanged version) (right)
2. DTS ARS-12K with special combine accelerometer/ARS mount (Humanetics part #
IT-900) on the standard bracket 020-1013A. The sensor and the mount are
shown in Figure 7.

3.5 Abdomen Pressure Twin Sensor (APTS)
Purpose
To measure loadings on the abdomen e.g. from CRS with shields or belt loading under
submarining. Injury criteria has been set under regulation R129. See for example
reference
7
.
Description
The sensors are polyurethane bladders closed with an aluminium cap and filled with
fluid. See figure 8. The pressure generated in the bladder is measured via a sensor in
the cap. The sensor design was developed by IFSTARR and is sold by Transpolis SAS.
The bladders come in three sizes 30, 40 and 50 mm diameter. The 40 mm diameter is
used on Q3.
Figure 8. 40 mm APTS sensor
The APTS are mounted inside a special abdomen assembly part number 020-5005. This
part has two blind holes for the sensors parallel to the lumbar spine. The APTS are
inserted aluminium cap down and the sensor cables come out through small holes at
the base on the blind holes. The bladders are put into Lycra sleeves to reduce friction
with the abdomen and held in place with Velcro at the bottom of the hole. The abdomen
assembly is delivered with foam plugs to facilitate standard certification of the abdomen
as in section 8.4. The Lycra sleeves are not used with the foam plugs.
The APTS have a higher density than the removed standard foam so there is an increase
to the abdomen of around 163 grams.
