Usually, detailed impact simulation models within flexible multibody systems have to be set up manually rather than being generated automatically. This is because the process requires prior knowledge of the time and location of the impact, as well as the element resolution within the contact area. If the penalty method is used to determine the occurring contact forces, the corresponding penalty factor also needs to be determined manually. This thesis presents an adaptive procedure to simulate impacts within flexible multibody systems fully automatically using reduced models based on the isogeometric analysis (IGA), the floating frame of reference formulation, and quasistatic contact models for an efficient but still accurate simulation.
