Abstract:
Aiming at the problems existed in the squeeze film damper of the
rotation machinery utilizing traditional passive dynamic
pressure film bearing, a project of dynamic pressure and static
pressure hybrid oil film bearing with piezoelectric crystal
electrohydraulic active control supply orifice hole is proposed.
For this kind of hybrid film bearing, the π film assumption can
not hold true. In order to solve the pressure distribution, a
new kind of solving method is proposed.
Key words: Hydraulic
control Squeeze film damper Rotor dynamics
