Do More Than Repair
TRI uses computer simulations to evaluate bearings . We use a vertically integrated process that goes from analysis and design to manufacturing and installation has resulted in an enviable experience record for both fixed bore bearings and tilt pad bearings. In the design process, TRI uses its proprietary computer programs to adjust the design in order to optimize oil film thicknesses, film pressures, bearing metal temperatures, and power losses, and at the same time, to suppress sub-synchronous rotor vibrations over the load range of the bearing application. For bearings from other manufacturers that have been damaged in service and are being repaired at TRI, we often propose design adjustments based on the results of TRI’s computer simulations.
