GUILLOTINE LOOK-ALIKE SAFETY TOOL
CD 2055020 E&MP2.001
November 16, 1967
A device resembling the notorious guillotine has found its place as a safety tool at the General Motors Proving Ground near Milford, Mich. This impact device drops an instrumented load cell on the chests of test dummies to calibrate -- or standardize -- the spring rate of the dummiesí chests.
These dummies are used to test the performance of production and experimental steering assembly designs on a special test fixture which slams the dummy against the wheel.
The impact device has been used by GM Proving Ground engineers to calibrate chest spring rates on all dummies used by the entire automotive industry for testing compliance with Federal Motor Vehicle Safety Standards.
By using only one device, engineers make sure that wherever the dummies are used test results can be compared accurately.
Several supplier and accessory firms also have had dummies calibrated on the Proving Ground equipment.
