In this paper, an experimental study is presented for the squeeze film problem between rigid and compliant surfaces with a central air source. The lower squeezing plate is a compliant one and is fixed to an electric vibrator. The upper squeezing plate is a rigid floating body supported by squeeze air film. The weight of the floating upper plate is 1.75 N to 3.75 N and the range of frequency of vibration is 0.5kHz to 1.8kHz. The effects of volumetric flow rate, exciting frequency and amplitude of the squeezing plate on the characteristics of squeeze air film are investigated. Numerical analysis is also conducted for a simplified model. It is found that the combined effects of static pressure of the central air source and squeeze effects improve the load carrying capacity and stability of the floating mass.
