Generalized model reduction method in dynamic of mechanical systems
Original language description
The contribution proposes modal reduction method of the dynamic systems composed of linear nonconservative subsystems coupled by nonlinear discrete couplings.Classical approach to the modal reduction is based on the transformation of the generalized coordinates by the real modal submatrix of the linear conservative part of the whole system. The generalized modal reduction method is based on the complex modal values of the whole system or the mutually isolated subsystems.Their complex eigenvalues and eigenvectors are used for transformation of the generalized coordinates and reduction of the number of degrees of freedom. The method is tested using three rotating blades with friction effects in contact surfaces of the blade shrouding.
