Development of an Advanced Thorax / Shoulder Complex for the THOR Dummy

Artikel i vetenskaplig tidskrift, 2013

Thoracic injuries are one of the main causes of fatalities and severe injuries in car crashes. The tools available today for studying these injuries are not up to par with the latest implementation of restraint systems and airbags. THORAX-FP7 is a collaborative medium scale project under the Seventh Framework. It focuses on the reduction and prevention of thoracic injuries through an improved understanding of the thoracic injury mechanisms and the implementation of this understanding in an updated design for the thorax-shoulder complex of the THOR dummy. The updated dummy should enable the design and evaluation of advanced restraint systems for a wide variety (gender, age and size) of car occupants. The hardware development involves fi ve steps: 1) Identifi cation of the dominant thoracic injury types from fi eld data, 2) Specifi cation of biomechanical requirements, 3) Identification of injury parameters and necessary instrumentation, 4) Dummy hardware development and 5) Evaluation of the demonstrator dummy. The THORAX project started in February 2009. This paper presents results achieved so far including outcomes of accident surveys, selection of human response data suitable for the assessment of the dummy performance, human body simulation into the injury criteria and the dummy developments done so far.
