Vertical Impact Tests of Humans and Anthropomorphic Manikins

Abstract

Small and large prototype Advanced Dynamic Anthropomorphic Manikins (ADAMs) along with CG-95 and CG-95 GARD manikins, were subjected to impacts up to +24 Gz on a vertical deceleration tower. Human subjects were also tested at levels of up to +10 Gz. The test variables were acceleration input and rise- time, seat-back angle, restraint harness, and seat cushion. Both the small and large ADAMs were found to be structurally sound at test up to +24 Gz. Data acquisition, however, was often incomplete, due mostly to broken wires, noisy channels, and circuit board failures. Both ADAM manikins demonstrated reasonable good repeatability of acceleration and force data in the direction of impact, although the channel sensitivities appeared to gradually change with repeated tests. The small ADAM appeared to demonstrate relatively consistent simulation of human dynamic response in the z-axis, but the large ADAM had a tendency to generate larger peak acceleration and seat force data than expected. Employing a Confor(TM) Foam seat cushion appeared to have almost no effect on human dynamic response. The X-Band 90 deg restraint harness appeared to outperform the PCU-15/ P harness in the human tests. Varying the seat-back angle + or - 10 degree significantly effected only the peak magnitude of the x-axis chest acceleration data.
