  5. 3. Journal bearing design, lubrication and operation for enhanced performance

    Author : Gregory F Simmons; Rob Dwyer-Joyce; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Maskinelement; Machine Elements;

    Abstract : The increasing introduction of intermittent power sources combined with the de-regulation of electricity markets has led to increased instability in the electrical grid. This has led to increased start-up and shutdown of regulating power sources such as hydro-electric power plants and operation at non-ideal operating states both of which increase the wear and tear on machines.

    Author : Matthew Cha; Sergei Glavatskih; Ilmar Santos; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Compliant Journal Bearings;

    Abstract : Plans to shut down nuclear power plants in some European countries as well as increased electricity production by wind and solar power will increase the work load on hydroelectric power plants in the future. Also, due to the power grid regulations, hydroelectric power plants undergo more frequent start-ups and shut-downs. READ MORE

  7. 5. Polymeric Materials for Bearing Applications : Tribological Studies in Lubricated Conditions

    Author : Arash Golchin; Luleå tekniska universitet; []
