Automobile crash test dummies are essential tools used by car manufacturers for safety testing. They simulate various parts and structures of the human body and are equipped with a wide range of sensors to record forces, accelerations, and movements experienced during collisions. This allows engineers to evaluate the protective performance of vehicle safety systems.
The dummy’s head consists of an aluminum skeleton covered with rubber as “skin.” Three accelerometers are installed inside to measure head acceleration and impact forces during collisions.
The neck is equipped with sensors to measure forces during a collision, including bending forward and backward, as well as lateral (left-right) motion.
The arms do not carry sensors and swing freely during a collision. While unrealistic compared to actual human movement, protecting the arms is critical, but there are currently no standard test indexes or measurement methods.
The chest contains metal ribs of the same size and spacing as human ribs, which are equipped with sensors to measure impact forces and deformation during frontal collisions, simulating the effect on a front-row occupant.
For side impacts, the EuroSID II dummy is used. Sensors are mounted on three ribs to measure the extent and speed of chest compression during a side impact.
The dummy’s abdomen includes a sensor to measure forces that could cause abdominal injuries.
A sensor installed in the pelvis records forces that could lead to joint dislocation or pelvic fractures.
Using the Hybrid III dummy, the thigh region (including pelvis, thighs, and knees) is equipped with sensors to record data during frontal impacts. In severe collisions, the femur may fracture or dislocate, and special sensors measure the impact force transmitted to the knee from the steering wheel.
Sensors in the calf measure the forces that could cause fractures, bending, or crushing injuries. They also monitor potential injuries to the knee, tibia, ankle, and connections between the bones.
Sensors measure the likelihood of foot injuries in frontal impacts. Injury probability is determined by deformation near the pedal area and the extent the foot is pushed into the vehicle.
Crash test dummies provide a comprehensive simulation of the human body in collisions, allowing accurate evaluation of automotive safety systems.
