| Abstract: | The amplitudes of a vibrating rotor can be depressed by means of setting a squeeze fluid film damper (SFFD). The dynamic characteristics of SFFD with complete round film are discussed in the paper.Expression for fluid film stiffness and damping of SFFD is derived. An analyses could be presented for building the vibration model of SFFD. |
