Abstract: Contact modeling is an active research area in the field of multibody dynamics. Despite the
important research effort, two main challenging issues, namely accuracy and speed, are not yet
jointly solved. One main issue remains the lack of model order reduction schemes capable to
efficiently treat systems where multiple, a priori unknown, input-output locations are present.
This work first analyzes the importance of including the necessary residual attachment modes
by numerical simulation of two gears meshing in an ad-hoc flexible multibody model. Given
the large number of residual attachment modes needed, the methodology named static modes
switching is extended and successfully applied to improve efficiency. The method proposes an
on line selection of residual attachment modes for accurate local deformation prediction. The
applicability to impact problems is discussed through numerical experiments and the automatic
selection strategy is based purely on geometrical information. Results show that the method
can be applied to gear meshing simulation, obtaining a high level of accuracy while preserving
computational efficiency. Comparisons are made between modally reduced models, full nonlinear
finite element and the proposed strategy
