Collision Performance, LM Safety Car 670458

Engineering evaluations of the collision performance for the Liberty Mutual Safety Car and the 1966 Chevrolet sedan were made, consisting of two 30 mph rear-end and two 40 mph intersection collision experiments. Methodology provided comparative analysis of functional characteristics for five types of seats, each studied for different exposure conditions. Five conditions of restraint were included for four sizes of occupants; the anthropometric dummies, their restraints, seats, and crashing cars all carried appropriate transducers. Seven high G-tolerant, high-speed cameras, carried by the crashing cars provided close-up continuous monitoring of these quarter-second collision sequences, supported by many more tower and ground level special photographic units arranged about the collision scene. Data from photographic, electronic and related instrumentation are presented using photographic and graphical techniques designed to facilitate comprehension.
