Abstract: Contact modeling is an active research area in the field of multibody dynamics. Despite
the important research effort of the last decades, two main challenging issues, namely
accuracy and speed, are far from being jointly solved. One main issue remains the
current lack of model order reduction schemes capable of efficiently treat systems
where multiple, a priori unknown, input-output locations are present. This work
discusses how a methodology named static modes switching can be extended for its
use in gear contact simulation. The method proposes an on line strategy for the
selection of residual attachment modes for accurate local deformation prediction.
The applicability of the method is discussed by means of several numerical
experiments. The result is an indication that the static modes switching underlying idea
can be applied also in case of impulsive phenomena like gear impacts. Moreover, a
numerical study on penalty factor values and number of eigenmodes and residual
attachment modes shows an interesting relation between these three quantities, the
dynamic behavior of the system and the solution accuracy.
Finally, some simulations are performed to compare the adopted model order
reduction strategy with a reference non-linear finite element simulation.
