The FTSS SID-IIs Small Side Impact Dummy (pronounced SID-2-s) is a new generation crash test dummy to specifically evaluate advanced automotive side impact protection systems, particularly side airbags. SID-IIs was jointly developed in 1994 and 1995 by First Technology Safety Systems and the Occupant Safety Research Partnership (OSRP) of the USCAR program. The dummy has been extensively tested worldwide and is capable of measuring over 100 data channels for injury assessment of the head, neck, arm, thorax, abdomen, pelvis and leg. Anthropometry is based on the Hybrid III 5th Female Dummy and also closely matches size and weight of the 12-13 year old child.

Simulation Models

FTSS offers highly detailed and fully validated Finite Element Models of its dummies in the codes LS-DYNA, PAM-CRASH, ABAQUS and RADIOSS, along with FE modeling consultancy services.

Dummy Features

Head and Neck

The head and neck are based on the Hybrid III 5th Female and are certified to biomechanical corridors simulating the small human response in a lateral impact. A fitted urethane shield prevents airbag interference with the chin and neck during inflation. The neck cable is insulated with plastic bushings to eliminate mechanical noise and ground straps through the dummy minimize electrical noise. Upper and lower neck load cells are available.

Upper Torso

The thorax uses Vascomax® ultra-high strength steel bands bonded with a polymer damping material to simulate the human shoulder, ribs and abdomen. The asymmetrical upper torso can be rotated 180 degrees for left or right impacts. Spine mounted, gimballed, linear potentiometers attached directly to the ribs for maximum response and calculation of V*C. Triaxial accelerometer packs can be attached to spine and ribs for V*C verification and acceleration based injury assessment. Load cells measure forces applied by the ribs to the spine box. A neoprene jacket covers the complete chest assembly with replaceable foam pads in the impact area. The stub arm is mounted to the shoulder through a three axis load cell. Triaxial accelerometer packs can be installed at the shoulder and the upper and lower arm for side airbag inflation injury assessment. A replaceable rubber insert in the shoulder improves calibration testing.

Lower Torso

A cylindrical straight stepped lumbar spine maintains the dummy in the upright seated posture. The pelvis is a machined assembly with detachable hard urethane iliac wings. The lower torso can be impacted from either side and uses disposable foam crush plugs for maximum repeatability. Design allows increased adduction and measures loads at pubic symphysis, acetabulum and ilium. The pelvis flesh is a detachable vinyl skin over urethane foam molded in the seated position. The legs are a modified Hybrid III 5th Female design available with full instrumentation.
