The National Highway Traffic Safety Administration (NHTSA) has utilized acceleration sled testing for decades to allow for the evaluation of occupant kinematics, occupant protection systems, and occupant exposure in many modes of accidents. Such systems have the advantage of being non-destructive, having relatively low turnaround time between tests, and precise control of input parameters. These systems usually involve placing some portion of a vehicle occupant compartment on a rigid sled and then accelerating the sled with a desired linear acceleration pulse profile. Such systems have been effective in the development and evaluation of air bag systems, seat belt restraints, and occupant interior surfaces. A roll simulator has been developed to allow for similar parametric testing of vehicle/machine occupant compartments.
