摘要: |
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. |
