Occupant response. The SIDH3 remained upright during the vehicle propulsion stage. The vehicle exited the side-impact monorail and began to slide sideways along the wet concrete runway. The drop off the monorail, coupled with the frictional forces between the tires and the wet runway, slowed the vehicle and induced a vehicle roll angle of 3.9° at impact. The roll angle and vehicle deceleration caused the SIDH3 to lean toward the driver door and make slight contact. The pole intruded into the occupant compartment forward of the dummy’s head and in line with the dummy’s pelvic region. Contact between the door and the dummy’s lower torso and pelvis occurred approximately 0.020 s after impact. The dummy torso was wedged between the seat and intruding door, the head continued toward the door and window and contacted the B-pillar before protruding through the open window (0.032 s). The femur and shoulder area made contact with the intruding door as anticipated. While the dummy’s head was outside the window, the truck continued to wrap around the rigid pole. The B-pillar was drawn toward the pole and struck the rear of the dummy’s head, forcing the head into the side of the rigid pole (0.058 s). The head was pinched between the B-pillar and rigid pole for approximately 0.050 s. While the head was pinched and stationary, the torso continued to bounce and recoil from the pole, bending and twisting the neck. The dummy rose up and leaned out the window enough that the left shoulder made contact with the rigid pole.

Inspection of the pole and vehicle interior revealed red, green, yellow, blue, and purple chalk on various surfaces, confirming contact from specific dummy parts. Blue chalk from the dummy’s face was found on the side of the rigid pole and red chalk from the rear surface of the head was found on the

B-pillar, confirming the pinching action between the B-pillar and the rigid pole. Red chalk was also found on the interior surface of the B-pillar, along with some green chalk. These colors indicate contact between the rear and side surface of the dummy’s head and the B-pillar, before the head exited the window. The purple chalk (shoulder/torso region) was found on the pole and the interior door panel. Yellow from the thigh was found along the interior door panel and arm rest. The SIDH3 remained upright in the driver seat after the test. The dummy remained wedged between the collapsed door and bench seat. As shown in table 8, the HIC (952 g’s), TTI (68 g’s), and pelvic injury (112 g’s) values are below the current side-impact safety performance standards specified in FMVSS 214.

Using the techniques outlined in NCHRP Report 350, the lateral OIV was calculated. The lateral OIV is based on vehicle c.g. lateral acceleration data. The computed lateral OIV was 7.3 m/s.
