  4. 2. Design, testing and analysis of journal bearings for construction equipment

    Author : Henrik Strand; Sören Andersson; Arto Lehtovaara; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Contact Mechanics; Finite Element; Grease; Journal Bearing; Lubrication; Replica Technique; Test Apparatus; Tribology; Wear; Mechanical manufacturing engineering; Mekanisk tillverkningsteknik;

    Abstract : Grease-lubricated journal bearings present a common challenge for construction equipment manufacturers in the world. The common design methodology is based on empirical data and has worked very well historically because the market and governments have accepted that bearings in construction equipment need frequent lubrication and exchange of worn parts.

  5. 3. Dynamic Performance and Design Aspects of Compliant Fluid Film Bearings

    Author : Matthew Cha; Sergei Glavatskih; Kyung-Woong Kim; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Compliant bearing; dynamic performance; design aspects; Machine Design; Maskinkonstruktion;

    Abstract : Due to government regulations together with health and safety reasons, there are increasing demands on reducing hazardous polluting chemicals from fossil fuel power plants. Therefore, more efforts are imposed on using renewable resources such as water, wind, solar and tide to produce clean/green electricity. READ MORE

  6. 4. 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.

  7. 5. Rotordynamic Modeling and Characterization of Support Elements in Vertical Machines

    Author : Gudeta Benti; Jan-Olov Aidanpää; Rolf Gustavsson; Ilmar Santos; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Rotordynamic; Support Element; Bearing; Squeeze Film Damper; Hydropower; Vertical Machine; Machine Design; Maskinkonstruktion;

    Abstract : The dynamic properties of rotating machines are highly influenced by interconnecting devices, such as bearings, seals, or squeeze-film dampers. They play a significant role in regulating the characteristics of the interaction between the rotating and stationary parts of the machines. READ MORE
