Structure：
Head--The head is largely made from polyurethane synthetics. The head cavity is large enough to allow use of several instruments, including linear accelerometers and a tilt sensor.
Neck--The neck is flexible and allows shear and bending in all directions. The segmented design prevents buckling and allows realistic rotational behavior. The neck is fitted with a flexible stainless-steel wire at its core to prevent failure under high load. A six-channel load cell can be mounted at the neck-head and neck-thorax interface.
Thorax--The chest of children is composed of a polyurethane skeleton and skin.The deformation can be measured with two IR-TRACC 2D sensors located in the upper and lower regions of the ribcage. The shoulders are connected with a flexible joint to the thorax, allowing deformation. Accelerometers can be mounted in the thoracic spine, ribcage and outer shoulder to measure linear accelerations. Moreover, the thoracic spine facilitates the use of angular velocity sensors and a tilt sensor. A side impact shoulder kit can also be fitted.
Abdomen--The abdomen is foam filled covered with a PVC 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 Q10 dummy pelvis has a different design from other Q-dummies. Its design is similar to the WorldSID dummy with an option to fit a single channel pubic symphysis load cell, two sacro-iliac load cells. The pelvis therefore has a more compliable design for side impact with plastic bones and a flexible rubber pubis.Space is also reserved for the installation of sensors.Accelerometers, angular velocity sensors, and a tilt sensor can be mounted in this space.Apply a frictional force at point H for the positioning of the hip joint.
Arms--The friction in the elbow joints and the shoulders can be adjusted to a one g setting. The side impact shoulder kit has a more compliant upper arm with no lower arm.
Legs--Six axis femur load cells can be fitted. The friction in the knee joints can be adjusted to a one g setting. The lower legs use the same part on both sides.

The Q-series dummy is a children's series dummy launched after the P-series dummy. Compared to the P series dummy, the biomechanical characteristics of the Q series dummy have been improved, based on the dummy response defined by the biomechanical information response curves of children and scaled down adults. This series of dummies can be equipped with acceleration sensors, angular velocity sensors, force sensors, displacement sensors, etc., to evaluate the damage suffered by the dummy in various situations.
In order to make the child dummy easy to install and disassemble, SF Company has optimized the dummy structure to ensure that the dummy can be quickly disassembled and assembled, and to minimize the impact of sensors on the dummy's motion characteristics, protecting the integrity of sensors and cables inside the dummy.
