Biodynamic Assessment of the THOR-K Manikin
Abstract
A total of 39 impact tests were conducted to support a test program to evaluate the THOR-K manikin's biodynamic response for potential use in the development of advanced occupant seating systems by NASA and the USAF. The principle objective of this evaluation was to determine the biodynamic response of the THOR-K with particular emphasis on measuring the spinal and restraint harness loading for various impact orientations and loading conditions. This data would also be compared to the Hybrid III 50th percentile manikin response data in select test configurations. Testing was completed in three impact orientations: +z-axis, +y-axis, and -x-axis, and with input accelerations at various impact G-levels that ranged from 8 to 20 G peak value. Testing was also completed to determine the frequency response of the THOR-K manikin by varying the time-to-peak G of the applied input acceleration from 30 ms to 100 ms. In general, the THOR-K provided good linear response across the various test conditions out to a 20 G input acceleration for the measured test parameters evaluated. The THOR-K response was maximized at the 30 ms time-to-peak input condition. The THOR-K responded in a similar fashion to the Hybrid III manikin in terms of peak values with the exception of the head and neck responses which were consistently lower regardless of peak input acceleration or the input acceleration's time-to-peak value.
