In-plane tangential relative motion is mostly two-dimensional.
In the finite element routine disk assemblies containing N sym- metric blades coupled tangentially through the rotor are analyzed.
As a first approach a single excitation force split into axial and tangential directions from the CFD-calculated pressure distribution maybe applied assuming a uniform radial distribution along the blade height.
l denotes the tangential position of the excited mode.
where refers to both axial and tangential directions.
