Kumar, Arun VM (1981) Influence of O-rings on the behaviour of damping coefficients in a squeeze film mounted ball bearing. In: nternational Symposium on Air Breathing Engines, 16-22 Feb. 1981, Bangalore, India.Full text not available from this repository.
The effect of O-rings on the behavior of damping coefficients is investigated using a squeeze film damper unit with a horizontal shaft configuration. Experimental values of the equivalent viscous damping coefficient are presented for three ranges of initial compressibility13; in the mounting of the O-ring and three values of rubber hardness. The inclusion of O-rings in the squeeze film damper unit increases the damping coefficient for larger film thicknesses with the effect found to decrease with film thickness. The hardness of the O-ring increases13; the damping coefficient whereas rotor speed and initial13; compressibility have little effect.
