摘要: Abstract A turbine blade system with dry friction between the shroud ring elements is analysed and results obtained by a finite element method, are presented. Friction forces in interacting surfaces described terms of anisotropic theory. In examples, frequencies mode shapes undamped free vibrations analysed. Vibration excitation due to vibration coupling caused anisotropy when initiated prescribed displacements or velocities.
