Lubrication of Sliding Bearings for Hydropower Applications

The influence of pad facing material on hydrodynamic lubrication in tilting-pad thrustbearings is investigated in terms of pad and oil-film temperatures and oil-film thickness. Two tilting-pad thrust bearings are examined: one with babbitt pad facing, the other with a layer of a PTFE based composite material. Frictional torque, pad, collar and oil-film temperatures and oil-film thicknes...

Control of structures with friction controllable sliding isolation bearings

A friction controllable sliding isolation system was developed and experimentally and analytically investigated by Feng et al. (Feng, Q., Shinozuka, M. & Fujii, S. A. friction controllable sliding isolation system. J. Eng. Mech., ASCE, 1993, 119(6), in press), the control algorithm having been developed based on a key assumption that the structural motion is always in the sliding phase. However...

Controllable Sliding Bearings and Controllable Lubrication Principles—An Overview "2279

Hydrodynamic and aerodynamic lubrication regimes in their controllable forms have been intensively investigated over the last two decades. With the aim of reducing friction and improving thermal, static, and dynamic characteristics of radial sliding bearings, different types of electro-mechanical actuators have been coupled to such bearings. Depending on (i) the actuator type; (ii) the actuatio...

Experiment of Ultimate Shear Failure and Friction Sliding Performance of Rubber Bearings of Bridges

The results showed that (1) the ultimate shear deformation of the rubber bearings with two fixed end plates reached 300% to 400% of the rubber layer thickness. The damage was mainly focused on the rubber layer fracture. The energy dissipation capacity of the bearings was weak, and the hysteresis curve presented a narrow zonal shape. (2) The rubber bearings with unilateral friction sliding had a...
