Reduced order modelling of non-linear gyroscopic systems in ALE formulation with frictional contact
(Own Funds)
Project leader:
Start date: 1. January 2015
Abstract:
Rotating systems are subject to gyroscopic effects, which influence the structure’s dynamics. The Arbitrary-Lagrangian-Eulerian formulation in the finite element method offers an efficient way to include translational and rotatory guiding movement in the model in the course of decoupling this motion from the FE mesh. At the same time this approach aggravates the computation of frictional contact of the rotating body with other still-standing structures.
This procedure stems from the field of rolling contact dynamics and is used in this project for the simulation of disc brakes. By means of these non-linear gyroscopic ALE-systems miscellaneous methods of reduced order modelling in structural dynamics are put to test and extended to meet the models peculiarities.
