After a bibliographic study on the existing experimentations, four sled tests were carried out with 4 cadavers under specially designed reproducible boundary conditions. Two tests were performed with 4kN load limiter device, the 2 other with 6kN limiter. These 4 tests allowed filling the lack of available data concerning the whole human body behaviour in a crash situation and were used afterward for the global Humos model validation.
Furthermore, prior to each PMHS tests, the full set-up was checked with H-III dummy. These results are of great interest to demonstrate the difference of the human body with regard to the dummy in a car-like situation.
In addition a very large experimental database was constructed to calibrate and validate the models of neck-shoulder-thorax-abdomen-pelvis complex. The definition of corridors was based on analysis of principal published biomechanical tests on the neck, shoulder, thorax, abdomen and pelvis, including a large spectrum of loading type, loading direction, and loading.
Interest: The data enrich a corpus of bio-mechanical references which can be used for various purposes, including software validation, accident reconstruction, predictive bio-mechanical simulations, dummy biofidelity assessment, etc.
Limits: No specific limits identified.
Potential: These results have an academic interest and should be published for use in the field of the biomechanics of impact.
An accurate definition of the inner and outer geometry of a 50th percentile human body in a driver position was achieved, including all bones and the most relevant organs, muscles and ligaments. The necessity to have a driver position geometry imposed the use of a method which consists of the physical slicing of a frozen cadaver secured in a driving posture. Each slice was 5mm thick and the saw was 2.5mm thick (268 slices were realised). The different slices were photographed, and then all the images were contoured, organ by organ, by skilled anatomists. This acquisition phase generated a set of about 13000 files representing 300 anatomic pieces; each file contained a set of points characterised by their 2D coordinates.
All these files were then used to create the CAD surfaces adapt for meshing purpose. During this reconstruction phase a back and forth process was set up between anatomists and CAD engineers in order to validate at each step the shape of the reconstructed surfaces.
Interest: The data are a unique reference for position and arrangement of human body organs when the body is placed in the posture of a driver.
Limitations: The human body investigated is one single sample, not exactly corresponding to a mean 50th percentile driver.
Potential: These results have an academic interest and should be published for use in the field of anatomy or other scientific research.
A thorough review of the literature was carried out on bones, muscles, ligaments, tendons, organs and joints. It resulted in gathering a wide range of materials laws and mechanical parameters. Then, specimens from human ribs, rib cartilage, pelvis, sternum and clavicle were investigated. All types of specimens were tested both statically and dynamically. More than 400 single experiments were performed on 73 subjects.
Static and dynamic muscle compression tests were also carried out with porcine femoris muscle. For each case, two directions of the muscle were tested: 1) x-transverse direction, perpendicular to the muscle major axis. 2) Z-longitudinal direction, along to the major axis of the muscle. The strain rate of the dynamic tests was up to 165(-1) and the ultimate deformation varied between 60% and 90%. For Quasi-Static rates at least five samples for the same condition were tested up to 80% compression.
Interest: The data enrich a corpus of bio-mechanical references which can be used for various purposes, including accident reconstruction, predictive bio-mechanical simulations, etc.
Limits: No specific limits identified.
Potential: These results have an academic interest and should be published for use in the field of the biomechanics of impact.
