Dassault Systèmes announced today the release of the Abaqus WorldSID (Worldwide Side Impact Dummy) 50th percentile male dummy model from SIMULIA, the Dassault Systèmes brand for realistic simulation. Vehicle safety engineers are able to utilize the new WorldSID model from SIMULIA to develop vehicle designs that enhance side impact protection and reduce injuries to occupants. Moreover, virtual crash tests involving simulation models for the vehicle and dummy can be carried out many times, much faster, and at far less expense than physical crash tests on costly vehicle prototypes.
Vehicle safety is one of the most important requirements in modern vehicle design. German car manufacturers Audi, BMW, Daimler, Porsche, and Volkswagen founded the Partnership for Dummy Technology and Biomechanics (PDB) in 2002 as a cooperative venture to combine their specialized knowledge in crash test dummy technology, biomechanics and simulation in order to achieve high standards of occupant protection.
SIMULIA has developed its Abaqus WorldSID 50th percentile male crash dummy model in collaboration with the PDB. The consortium has recently approved Version 2 of the Abaqus model, confirming the close correlation of the model against numerous physical tests carried out on the corresponding dummy hardware.
Due to its enhanced true-to-life design (known as, biofidelity), the WorldSID 50th dummy hardware is being incorporated into crash testing regulations around the world. The model is representative of the average male in terms of height, mass, and proportion. Various improvements to the dummy design over previous side impact crash dummies, such as incorporation of Nitinol material in the rib cageregion, lead to the improved biofidelity of WorldSID. The Abaqus WorldSID 50th development process has validated the dummy simulation against nearly 300 separate physical calibration tests for material, component, subassembly, and full dummy load cases.
"The Abaqus WorldSID dummy model is a critical development in our ongoing strategy to expand our automotive crashworthiness and occupant safety simulation solutions," said Ken Short, VP, Strategy and Marketing, SIMULIA, Dassault Systèmes. "It further enables automotive OEMs to carry out a simulation-driven design process, employing dozens of accurate simulations to design and refine the passive safety features in their vehicles. With Abaqus, automotive companies now have the ability to leverage the power of robust simulation solutions across multiple engineering disciplines in order to improve all aspects of vehicle design"
