Dynamic properties of a turbine blade couple: Analysis of the contact force effects
Original language description
The contribution is concerned with modelling of a harmonically excited turbine blade couple with frictional contact of shrouds and analysing the effects of compressive normal and tangential friction forces on dynamic properties of the blades. The turbine twisted blades (that are considered to be clamped into a rotating rigid disk) are modelled by means of the finite element method using Rayleigh beam elements with varying cross-sectional parameters and six degrees of freedom in each of nodes. The rhomboid-shaped shrouds are considered to be rigid. The modelling of interactions at the contact surfaces is carried out using a multipoint frictional contact model with constant normal contact stiffness.
