3.3 Design and analysis of a support with a Hydrodynamic damper and flexible element

3.3.1 Topics.

In a support furnished with a Hydrodynamic Damper and flexible Element (HDFE) the oil film has low bearing ability at small eccentricities, in other words the FE stiffness is much higher than the film stiffness. It permits to have constant support stiffness and to obtain high damping in a not cavitated damper.

Oil film stiffness and damping can be calculated equally to a HD without an EE.

Below are given some specific features of a HDFE:
