Development of Advanced HIII Abaqus dummies

Abstract: Hybrid III dummies are among the most frequently used dummies in both industry and academia for vehicle crash safety. Abaqus is one of most widely applied finite element codes in the world. To meet the needs of crash safety analysis and to exploit the potential of the Abaqus/Explicit code, a family of HIII dummies, including HII 50th male, 5th female and 95th male dummies, were developed at FTSS in collaboration with Simulia and BMW. This paper describes in detail the development of the HIII dummies with specific reference to the HIII 50th dummy. Firstly correct material models based on material test data are verified. Secondly variety of FTSS standard (certification-based) and non-standard finite element validation tests at component level, i.e. head drop, neck pendulum, lumbar spine, knee slider, knee impact and single rib tests, and at full dummy level, such as thorax pendulum, sled seatbelt and sled airbag tests, were accomplished. In addition, a suite of extra test, developed by the Partnership for Dummy Technology and Biomechanics (PDB), was integrated into the dummy development to enhance the fidelity and robustness of the dummy performances. Those tests include head impact (forehead and cheek), thorax impacts, tibia tests and foot and shoe tests. Based on these series of stringent validation tests, a family of HIII dummies have been successfully developed, which greatly facilitates virtual vehicle development and design process of the occupant safety in the automotive industry.
