Original abstract
The deformation of the vehicle as a result of the accident serves as the input for determining the impact speed for the purposes of the expert report. One possibility of calculating the impact speed is by means of a verified finite element analysis (FEA) of the vehicle impact. However, to develop such a sufficiently accurate finite element (FE) model requires a significant financial and time investment. Such a model contains a number of key simplifications that are difficult to detect without prior experience. Fortunately, there are at least a few freely available detailed FE vehicle models that have been experimentally verified. On these it is possible to investigate the effect of different modelling methods on observed parameters such as overall deformation. This paper is specifically concerned with the sensitivity of FEA results to different levels of vehicle geometry modelling. A Chevrolet Silverado 1500, model year 2014, is used as a detailed FE vehicle model.
