The paper presents the results of an experimental investigation in which the damping coefficients of a squeeze-film bearing are obtained from impedance measurements. For various force levels, and for frequencies up to 200 Hz, the bearing length, radial clearance, and viscosity are varied and both the concentric and the eccentric case are investigated. Good correlation is found with a simplified linearized theory for moderate force levels, and for higher force levels the correlation is satisfactory when the oil supply pressure is increased sufficiently.
