Abstract : The response of an operator to simulated ship shock was evaluated for a subject seated on the Special Purpose Operator's Chair (SPOC). An instrumented Hybrid III manikin was vertically impacted at levels from 3 to 30 Gs on the Naval Biodynamics Laboratory's (NAVBIODYNLAB) Vertical Accelerator, adjusted to simulate ship Z-axis response to underwater explosions; the 30 G level exceeds the maximum values observed in several ship shock trials. The experiments were conducted using both the SPOC and two versions of a hard-bottomed seat in order to evaluate the shock attenuating capability of the SPOC. The evaluation of the capability of the Vertical Accelerator to accurately simulate ship shock and to produce repeatable results was also a goal of this program and was successfully achieved.
