Sophisticated devices

Crash test dummies are known as anthropomorphic test devices (ATDs). Dummies must mimic the dimensions, weight distribution and joint articulation of the human body and are capable of measuring the forces on the body in a vehicle crash.

Crash test dummies are highly sophisticated instruments with some measuring injury in frontal crashes, while other measure injury in side–on crashes. They carry an extensive set of sensors that measure the forces and accelerations experienced by the dummy in a crash.

Crashlab has a large family of crash test dummies, representing adults and children of various sizes. They are used in vehicle crash tests to determine the risk of injury for human occupants. Child dummies are used to evaluate the protection provided by child car seats and booster seats.

Dummies repaired and calibrated

Each crash test dummy must be in “as new” condition each time it is used in a test. This ensures that the readings recorded are a measure of the performance of the vehicle or child car seat, rather than the condition of the dummy. Crashlab has a comprehensive dummy maintenance and calibration laboratory with experienced technicians to repair and validate the response of each dummy before it is returned to service.

Constant maintenance and calibration ensures that the dummies have a long life in the service of vehicle development and road safety.

Crashlab’s frontal, side impact and child dummies and calibration services support full certification across the following testing regime.
