Simple optimization techniques may serve well for the improvement of product performance at early concept design phases. At final phases though, optimization problems become more complex, with many variables and multiple optimum ...

The Integrative Approach described in this paper incorporates effects of the part’s manufacturing process (here: injection molding) into a new workflow for optimization of the part performance. The new approach is able to close the ...

Deck arresting gear is a special aero-carrier unit that is destined to provide an efficient arrestment of the deck jet-fighters of masses 10-25 tons with high landing velocities between 180 and 240 km/h. Main elements of the modern ...

A biofidelic flexible pedestrian legform impactor (Flex-PLI) has been developed by Japan Automobile Manufacturers Association, Inc. (JAMA) and Japan Automobile Research Institute (JARI). The Flex-PLI has good biofidelity as well as ...

Validation of occupant lower leg injury performance is a difficult procedure due to the complex interaction between occupant and vehicle structure. As a starting point, a carefully validated structural model is crucial to ensure the ...

While safety legislation becomes more stringent and vehicles intended for global markets must conform to the requirements of a wider range of regulatory bodies, the cost of physically testing crash safety performance continues to rise ...

Legal and consumer crash tests use crash dummies as the key measurement device in the assessment of crash severity. The dummies are complex assemblies in themselves, and sophisticated DYNA FE models are available, with a significant ...

An accurate Out-of-Position (OoP) simulation will be a mile stone for the development of restraint systems, as this would save hundreds of expensive hardware tests. OoP load cases are currently required by the US legislation and as ...

A detailed review of an existing LSDYNA finite element (FE) model of the Knee-Thigh-Hip (KTH) of a 50th percentile male was accomplished. The main scope was to refine some aspects of the model for obtaining a more appropriate and ...
