3D FE modelling of non-linear dynamics of bladed model disk with dry-friction contacts in tie-bosses
Original language description
The numerical solution of the turbine bladed wheel with tie-bosses based on 3D finite element method with surface to surface dry friction contact model is proposed. The Augmented Lagrangian method was used to compute contact normal pressures and friction stresses. The friction coupling was modeled by the Isotropic Coulomb’s law. To validate the numerical results, the experimental set-up for studying dynamical behavior of the bladed wheel with pre-stressed dry-friction contacts in tie-bosses was built. Both experimental and numerical solutions of the non-linear dynamics of bladed wheel with tie-bosses are described. Comparison of experimental and numerical results of dynamical behavior and damping estimation of our bladed wheel design yielded a reasonable agreement. However, the non-linear solution due to dry friction contacts leads to high performance computations and still long computation times.
