Abstract
Nowadays virtual testing and prototyping are generally accepted
methods in crash safety research and design studies. Validated
numerical crash dummy models are necessary tools in these methods.
Computer models need to be robust, accurate and CPU efficient,
where the balance between accuracy and efficiency is depending on
the nature of the study performed.
This paper presents the application of advanced
multibody-modelling techniques, in order to generate crash dummy
models that are accurate as well as CPU efficient. Two techniques,
deformable body modelling and arbitrary surface modelling, are
combined. Their application is presented by means of an example
model: the Hybrid III 50th percentile thorax. The method for
generating the model is explained, after which the accuracy and
efficiency of the model is illustrated by presenting some
simulation results.
