Pressure performance for a thin-walled ring and turbulent-jet orifice modeled elastic squeeze film damper
文献摘要：
This paper explores an analytical model for Elastic Ring Squeeze Film Damper(ERSFD)with thin-walled ring and turbulent-jet orifices,and uncovers its Oil Film Pressure Per-formance(OFPP).Firstly,the ring deformation is addressed by using the Fourier series expansion approach and the orifice outflow rate is characterized with the Prandtl boundary layer theory.Sec-ondly,applying finite difference scheme,the influence of elastic ring flexibility,orifice diameter,and attitude angle on the OFPP is analyzed.Finally,Outer chamber pressure was measured experimen-tally at different rotor speeds.The results indicate that the outer chamber pressure coats an individ-ual load-carrying region and spreads symmetrically pertaining to the attitude angle.Its amplitude drops as the elastic ring flexibility decreases but boosts with the reduction of the orifice diameter.For inner chamber pressure,the orifice diameter effects a similar trend to the outer cavity,but exhi-bits more stable distribution regarding the attitude angle.Minimizing the elastic ring flexibility causes an increase in amplitude.The model is validated by the test results giving that the outer chamber pressure shifts synchronously and periodically with the variation of the attitude angle,while the pressure amplitude increases slightly at higher rotor speeds.
