DS Releases Male Dummy for Virtual Crash Tests

Dassault Systemes (DS), a specialist in 3D and product lifecycle management products, has released the Abaqus Worldwide Side Impact Dummy (WorldSID) 50th percentile male dummy model from Simulia. Vehicle safety engineers can utilise the new WorldSID model from Simulia to develop vehicle designs that enhance side-impact protection and reduce injuries to occupants. In addition, 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, according to the company.

German car manufacturers Audi, BMW, Daimler, Porsche and Volkswagen founded the Partnership for Dummy Technology and Biomechanics (PDB) in 2002 as a co-operative venture to combine their specialised 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.

Thanks to its 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 ribcage region, improve the 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.

Ken Short, vice-president of strategy and marketing for Simulia at DS, said: 'The Abaqus WorldSID dummy model 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,' he added.
