BioRID-II Dummy Model Development -Stochastic Investigations

Whiplash injuries may occur in low speed rear crashes. Many consumer and insurance organizations use the BioRID-II dummy as test device, to assess the risk of whiplash injuries in car accidents. An LS-DYNA model of the BioRID-II dummy has been developed by DYNAmore GmbH in cooperation with the German Automotive Industry. This paper describes the current validation state and shows the latest modifications of the BioRID-II model. The emphasis is to discuss observations made during validation. Additionally, the paper describes a robustness study of a validation load case. Robustness studies are performed during validation in order to investigate dependencies and stability of the measured quantities. For this a Monte Carlo Analysis using LS-OPT [7] is applied and statistical quantities are evaluated and displayed.
