Design And Application Of Squeeze Film Dampers For Turbomachinery Stabilization

摘要: The steady-state transient response of the squeeze film damper bearing was investigated. Both and equations for hydrodynamic forces are derived; were used to determine equivalent stiffness damping coefficients. These coefficients find configuration which will provide optimum support characteristics based on a stability analysis rotor-bearing system. effects end seals cavitated fluid included. systems conducted by coupling rotor integrating forward in time. unbalance, cavitation, retainer springs Methods determining system under influence aerodynamic internal shaft friction discussed.
