An Advanced Database of the 50th Percentile Hybrid III Dummy

Abstract

<div class="htmlview paragraph">This paper presents a measurement program of a sitting 50th percentile Hybrid III Dummy to determine a database for computer simulations. Geometrical, inertial, joint property and surface compliance measurements have been carried out. A description of the measuring methodology is given.</div> <div class="htmlview paragraph">On the basis of these measurements a 20 segment database for the MADYMO 3D occupant simulation program is developed. The major advancements of this database compared to an earlier 15-segment database developed by TNO [<span class="xref">1</span>]<span class="xref">*</span> can de summarized as follows:</div> <div class="htmlview paragraph"> <ul class="list disc"> <li class="list-item"> <div class="htmlview paragraph">Five additional segments are incorporated in this database to account for the hands, the shoulders(clavicles) and the sternum.</div> </li> <li class="list-item"> <div class="htmlview paragraph">The database includes a complete omni-directional description for the neck as well as the lumbar spine.</div> </li> <li class="list-item"> <div class="htmlview paragraph">A detailed mathematical surface description is available, for instance to be used for computer animations.</div> </li> <li class="list-item"> <div class="htmlview paragraph">Segment ellipsoids for contact interactions have been determined in a more accurate way.</div> </li> <li class="list-item"> <div class="htmlview paragraph">Joint properties are determined with a special developed static joint measuring device.</div> </li> <li class="list-item"> <div class="htmlview paragraph">Segment surface and thoracic stiffness data are based on a large series of tests with different impactor faces, including tests with a seat belt.</div> </li> </ul> </div>
