The results of biomechanical testing of the WorldSID prototype dummy are presented in this paper. The WorldSID dummy is a new, advanced Worldwide Side Impact Dummy that has the anthropometry of a mid-sized adult male. The first prototype of this dummy has been evaluated by the WorldSID Task Group against previously established corridors for its critical body regions. The response corridors are defined in the International Organization of Standardization (ISO) Technical Report 9790. The prototype is the first version of the WorldSID dummy to be built and tested. This dummy has been subjected to a rigorous program of testing to evaluate, first and foremost its biofidelity, but also its repeatability. Following this initial evaluation, any required modifications will be incorporated into a pre-production version of the WorldSID dummy so that it rates “good” to “excellent” on the ISO dummy biofidelity scale – a rating exceeding that of all current side impact dummies.

Improvement of pedestrian safety is considered a priority in crash injury protection. Dummies, however, are not able to give a humanlike and repeatable impact response in pedestrian tests. The Biomechanical Laboratory of ONSER in France and the Department of Traffic Safety of Chalmers University in Götheborg, Sweden have designed a new dummy for pedestrian testing. The dummy is designed according to the latest available anthropometric and biomechanical data. Its symmetry around the vertical axis allows repeatability for the kinematic and injury parameters. It allows a measurement of uncommon biomechanical parameters related to injury mechanisms. Its leg is instrumented to determine the distribution of forces and momenta applied to the leg.

During the phase IV of the EEC biomechanical programme, the available side impact dummies were evaluated and this work concluded that none of the dummy was acceptable. The European Experimental Vehicle Committee set up a working group to built a new side impact dummy to be used in a standard side impact test. The ONSER laboratory was in charge of the development of the pelvis. This paper includes the specifications for the pelvis, agreed by the EEVC working group dealing with this subject, anthropometric analysis to choose sizes and mass distribution a description of the shape of the pelvic bone and the location and the type of transducer (force, acceleration). The design of the hip joint and the use of deformable materials to simulate the pelvic bone deformations are discussed. Results of impactor tests using a dummy fitted with this pelvis are analyzed and their results compared to those of cadavers tests conducted previously.
