Measurement of Spinal Loads in Two Modified Anthropomorphic Dummies.

摘要

The new generation of U.S. Army helicopters possesses unprecedented crashworthiness. Although these seats are far superior to any prior systems, there are several areas of uncertainty in the design criteria that require additional research to enable further progress to be made in the hardware. Research efforts were designed to meet the following objectives: (1) Establish the sensitivity of seat and occupant response to system variables. (2) Determine the effect on system performance of the type of dummy being used for testing and establish an appropriate standardized dummy for seat system evaluation. (3) Investigate the performance of the seat with an occupant more nearly representative of the operational occupant than are anthropomorphic dummies. Cadavers were to be used for this investigation. (4) Establish, through dynamic testing, additional information concerning human tolerance to accelerative loads in the + G sub z direction.
