Abstract EN
The contact surface structure of dry friction damper is complicate, irregular, and self-similar.
In this paper, contact surface structure is described with the fractal theory and damping blade is simplified as 2-DOF cantilever beam model with lumped masses.
By changing the position of the damper, lacing and shroud structure are separately simulated to study vibration absorption effect of damping blade.
The results show that both shroud structure and lacing could not only dissipate energy but also change stiffness of blade.
Under the same condition of normal pressure and contact surface, the damping effect of lacing is stronger than that of shroud structure.
Meanwhile, the effect on changing blade stiffness of shroud structure is stronger than that of lacing.
This paper proposed that there is at least one position of the blade, at which the damper dissipates the most vibration energy during a vibration cycle.
