Abstract
Performance and quality of joined assemblies depend on the joining technology and its characteristics. To predict these characteristics in advance simulation tools are used. This paper deals on the one hand with determining the results quality of 2D rotational simulations to predict characteristics of mechanical joining technologies and on the other hand with the results quality of simplified models to predict car body quality (shape, gap, flush). Compliance of 2D simulations and experimental results is shown by performing investigations with different setups looking at joints' quality and caused distortion. Finally, the results of joining simulations for car body assemblies are compared to measurements.
