Abstract

A new infant dummy has been designed, manufactured, and tested, representing an average newborn of mass 3.4 kg. This dummy is a successor of the 2.5 kg newborn dummy developed earlier which had represent at 10th percentile Japanese newborn. Gross data such as total weight, length, and head circumference were taken from several sources including the Centers for Disease Control [CDC, 2000]. More detailed measurements were obtained from newborns in two Japanese clinics. Dynamic response data for head, neck, thorax, and abdomen were defined by scaling adult data. The dummy has 11 segments (head, neck, torso, upper arm, lower arm and hand, upper leg, lower leg and foot). The torso is further divided into shoulder, chest, abdomen, and pelvis, all connected to a flexible spine. Segments are connected by joints which provide human like range of motion. The dummy is instrumented with 26 sensors, including triaxial accelerometers at the head CG, upper and lower neck, thorax CG and pelvis CG; 3-axis angular velocity sensor in the head; uniaxial load cells in the neck and lumbar spine; string potentiometer to measure chest deflection; and five force sensors on the abdomen. This paper describes the methodology used to develop the design and the results from biofidelity testing.
