2019-04-02 - Occupant Crash Simulation Analysis Made Easy 2019-01-1036

Over 30 years of occupant crash safety simulations have seen ever more sophisticated tools and models to keep pace with ever more demanding and expanding requirements. These sophisticated tools, however, require highly trained and experienced analysis specialists to operate. This keeps them out of reach of occasional users such a program managers, restraints buyers, and design engineers. Yet, the people involved in the early stages of vehicle development can have a great impact on vehicle safety performance and the costs of achieving the targets. By combining prebuild models and a fully capable finite element solver with an easy to use web interface, we aim to make the simulation technology available to anybody with a web browser. The application is richly featured. Alike to sled testing, there is a choice of multiple vehicle geometries, from sub-compacts to large trucks. They come with crash pulses that are typical for their class that may be scaled up or down to make them more or less severe. If that does not suit the purpose, a custom crash pulse may be designed by the user to match a specific vehicle or test condition. A great feature is that design details that are not part of a subject study can be left unspecified as the application will provide sensible defaults. If desired, however, primary restraint systems, such as airbag and seat belt systems, can be specified in great detail. The ease of use allows simulation analysis to be integrated at all levels and aspects of the business, and thereby make efforts to optimize occupant crash safety more effective. It also brings occupant crash analysis to groups that previously may not have had direct access, such as policy makers, students, and accident investigators.
