1. Introduction
In the late 1970’s and early 1980’s, 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 with the development of
a new series of child dummies as a successor to the P-series. This new series was called
the Q-series.
As of September 2004 the series is available in four age groups, representing a 1 year,
1½ year, 3 year and 6 year old child. A new born dummy, Q0 is also available. In 2004 a
major update of the Q-dummy series has been performed resulting in the completion of
the series from Q0 till Q6. The Q1.5 dummy and the Q0 were added to the series, and
modifications were made to enhance durability and measurement capabilities.
Part of the development of the Q-dummies has taken place within the European Research
programs CREST
1
, and CHILD
2
both aimed at improving child safety in cars.
Humanetics reserves the right to make improvements or implement changes to the
dummy, the certification or the users’ manual if this is deemed necessary. We will of
course inform our customers of any changes or modifications as they occur.

2. General Description and Features
2.1 Design History
In 1993 the international Child Dummy Working Group started with the development of
a new series of child dummies as a successor to the P-series. This new series was called
the Q-series. This development resulted in a Q3 dummy in 1998, later the Q6 (1999) and
the Q1 (2000) were added to the series.
Based on customer feedback and test results Humanetics have received comments on the
dummies performance and durability. This has resulted in an update program that was
started in 2004; this update 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 has 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-44 test was published in 2008. Results of the first evaluations have
been published ant the 19th Enhanced Safety of Vehicles conference in 2005
3
. 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 Q-dummy is a frontal impact child dummy, which is intended for both homologation
and research purposes. Possible applications include:
Child Restraint Systems (CRS) testing. This includes the European ECE R44 and the US
FMVSS 213 regulations. The Q-dummies have been designed to succeed the P-
dummies in CRS evaluation regulations.

2.3 Features
The Q dummies have improved biofidelity over the P-series. Biomechanical information
from children and scaled adult biomechanical response curves have been used to
define the dummy response. The anthropometry of the dummy has been 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 and high
yield strength, low stretch synthetic fiber cord in order to prevent excessive elongation.
The neck-cord is also designed to act a safety in case of rubber failure. A six channel
load cell can be mounted at the neck-head interface.
Thorax
The thorax of the child is represented with a single rib-cage. The deformation can be
measured with a string potentiometer. 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.

036-9900 User Manual Q1 (Advanced 1 year old child) Rev H Page 10 of 86
© 2016 Humanetics Innovative Solutions
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.
2.4 Instrumentation options Q1 dummy
The complete list of instrumentation options include:
Head Ax, Ay, Az linear acceleration.
Head Wx, Wy, Wz angular velocity.
Upper Neck Fx, Fy, Fz forces and Mx, My, Mz moments.
Thoracic Spine Ax, Ay, Az linear acceleration.
Thorax 'ribcage' Dx or Dy deflection.
Lower Lumbar Spine Fx, Fy, Fz forces and Mx, My, Mz moments.

3. Instrumentation
3.1 General
The dummy accepts both accelerometers and load cells as standard instrumentation.
Angular velocity sensors 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
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
(model IF-217 or IF-218) can be placed in the upper neck and lumbar spine location.
3.2 Transducers
The Q1 dummy can be fitted to measure of the following parameters:
Head
Standard - 3 uni-axial accelerometers in head (Ax, Ay, Az)
Optional - 3 angular velocity: Applied Technologies Associates, ARS-06S
-3 angular velocity DTS ARS-12K
Neck
Standard - Upper neck 6 channel load cell, 3 forces, 3 moments (Fx, Fy, Fz, Mx, My,
Mz).
Model IF-217 (350 Ohm) or IF-218 (120 Ohm).
Thorax
Standard - 3 uni-axial accelerometers (or tria-xial accelerometer) in upper spine (Ax,
Ay, Az).
- 1 string potentiometer to measure chest deformation, frontal or lateral
(Dx or Dy)
Optional - additional accelerometers may be installed on the thorax and the rib
cage (see notes below) (Ax, Ay).

036-9900 User Manual Q1 (Advanced 1 year old child) Rev H Page 14 of 86

Notes:
1. The string potentiometer may be mounted in two ways, either to measure frontal or
lateral deformations. The string potentiometer must not be used in deformations with
expected rib- deformation speeds exceeding 5 m/s.
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 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.
Note that this method gives an approximation of the actual deformation. The
accuracy is decreased due to the fact that the accelerometers cannot be properly
aligned during the test. 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 error is approximately 10%. At 6.7 m/s it is
approximately 20%.
