Abstract: The aim of the FIMCAR project is to develop and validate a frontal impact assessment approach that considers self and partner protection. In order to assess the influence of different test procedures and metrics on car-to-car compatibility a huge simulation programme was executed. However, car-to-car simulations with models of different car manufacturers are almost impossible to obtain because of confidentiality. In order to overcome these problems, parametric car models (PCM) were built, allowing fast modifications and more detailed generic car models (GCM) were developed for structural interaction analysis. Three different PCM representing a super mini, a large family car and an executive car were developed. By simplifying the models, computational efforts are reduced. Due to the parametric design it is possible to modify the models in an easy and fast way. The models are delivered in three crash codes (LS-DYNA, PAM-CRASH and RADIOSS) in order to be usable at all FIMCAR OEMs. The Generic Car Models (GCM) model virtual cars which represent an average real car of the respective category (super mini, small family car, executive car) in a comparable way to the OEM models. All together five different models were generated (2 super minis, 2 small family cars and one executive), again delivered in three different FE codes (LS-DYNA, PAM- CRASH and RADIOSS). The models can be used to evaluate the behaviour of the crash structure (e.g., crash pulse, deformation characteristics and intrusions). For supermini and small family categories, two models were generated in each class in order to describe the two main architectural/structural car variants that can usually be found on the road, i.e. with and without a lower load path in the frontal frame (structural elements below the main rails); the availability of both structural solutions in the GCMs is in fact important for the study of compatibility issues.
