Abstract:
A method of conducting crash tests using a crash-test carriage, said crash-test carriage being accelerated in accordance with a real deceleration curve to thereby simulate deceleration forces associated with a real collision, said crash-test carriage having a carriage drive apparatus associated therewith, the method comprising the steps of:exerting an accelerating force on said crash-test carriage in an acceleration direction, said accelerating force exceeding a respective force required for acceleration in accordance with the real deceleration curve; and exerting a braking force on said crash-test carriage in a direction opposite said acceleration direction in order to achieve a desired acceleration curve, said braking force being applied on one of said crash-test carriage and said carriage drive apparatus, said braking force controlled so as to accelerate said crash-test carriage in accordance with the desired acceleration curve.
