An Analysis of Injury Mechanisms for Ankle/Foot Region in Frontal Offset Collisions

This paper contains the results of 50% offset frontal collision tests which were conducted in order to analyze impact situation of ankle/foot regions during car-to-car crashes with both 50km/h running speeds. We took high-speed films of the footwell regions, and measured impact forces of Hybrid-III lower legs, three-axis accelerations of the toe-board, floor and brake pedal in the tests. In the same collision configuration, we conducted the tests under four different test conditions of driver seating situations as follows: with seatbelts + stepping on the brake pedal, with seatbelts + stepping on the accelerator pedal, without seatbelts + stepping on the brake pedal, and without seatbelts + stepping on the accelerator pedal. In this paper, we focused on motions and impact forces of lower legs, on intrusions and movements of the floor, toe-board and pedals, and on interactions with them during crashes.

WorldSID Prototype Dummy Biomechanical Responses

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.
