Abstract
The WorldSID 5th percentile dummy, representing an average female, was developed in less than three years after the WorldSID 50th percentile dummy production release. This 5th percentile dummy was developed in the Integrated Project Aprosys (Advanced Protection Systems) under the European Commission Framework Program 6. This paper discusses the rationale for the WorldSID 5th percentile dummy design and development, and biofidelity evaluation results of head drop test, neck pendulum test and pendulum impact tests of the shoulder, thorax, abdomen and pelvis according to ISO TR9790 (ISO 1997) and Irwin (2002). The dummy was designed to host four units of 32 channel in-dummy Data Acquisition System with total 128 channel capacity. The head is constructed with PVC skin and plastic skull to simulate human head structure. The neck consists of a rubber design with metal discs, which can be tuned with rubber buffers. Super-elastic nickel titanium alloy, Nitinol®, was used for the shoulder, thorax and abdomen rib design. The Nitinol® material has a unique damping property, which provided enough damping effect for the upper torso structure. This unique property allows eliminating the traditional temperature sensitive polyvinyl base damping material. The pelvis has a polymer construction that simulates the human pelvic bone structure. The biofidelity evaluation results are presented in this paper. According to ISO TR9790 rating guideline, the rating scores are defined as:
- Excellent Biofidelity: 8.6 ≤ B < 10.0
- Good Biofidelity: 6.5 ≤ B < 8.6
- Fair Biofidelity: 4.4 ≤ B < 6.5
- Marginal Biofidelity: 2.6 ≤ B < 4.4
- Unacceptable Biofidelity: 0.0 ≤ B < 2.6
The tests conducted show that the overall biofiedlity is rated at 5.5 according to ISO TR9790 specifications, and can be improved to 8.4 with further refinement.
