  2. 1. Prediction and experimental validation of dynamic soil-structure interaction of an end-bearing pile foundation in soft clay

    Author : Freddie Theland; Jean-Marc Battini; Amir Kaynia; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Dynamic soil-structure interaction; Pile group; End-bearing piles; Dynamic impedance; Environmental vibration; Experimental validation; Dynamisk jord-struktur-interaktion; Pålgrupp; Spetsbärande pålar; Dynamisk impedans; Omgivningsvibrationer; Experimentell validering; Structural Engineering and Bridges; Bro- och stålbyggnad;

    Abstract : In the built environment, human activities such as railway and road traffic, constructionworks or industrial manufacturing can give rise to ground borne vibrations. Such vibrations become a concern in urban areas as they can cause human discomfort or disruption of vibration sensitive equipment in buildings. READ MORE

  4. 2. 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

  5. 3. Gearbox noise : Correlation with transmission error and influence of bearing preload

    Author : Mats Åkerblom; Sören Andersson; D. Houser; KTH; []
    Keywords : gear; gearbox; noise; vibration; transmission error; bearing preload; Mechanical engineering; Maskinteknik;

    Abstract : The five appended papers all deal with gearbox noise and vibration. The first paper presents a review of previously published literature on gearbox noise and vibration. The second paper describes a test rig that was specially designed and built for noise testing of gears. READ MORE

  6. 4. Vibrations in timber floors : Dynamic properties and human perception

    Author : Kirsi Jarnerö; Anders Professor; Tomi Toratti; Linnéuniversitetet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; wooden floor; timber floor; vibration; design criteria; damping; frequency; questionnaire; field test; socio-vibrational survey; vibration annoyance; vibration disturbance; Byggteknik; Civil engineering;

    Abstract : Springiness and vibrations of timber floors are familiar to many as a ‘live’ feelwhen walking on them, especially if living in single family housing with timberframework. Since the building regulations in Sweden changed to performancedependentrequirements in 1994 the use of timber in multifamily housing hasincreased. READ MORE

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

    Author : Arash Golchin; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Machine Elements; Maskinelement;

    Abstract : One of the most important demands in hydropower and other industries today stems from the emphasis on preserving the environment. Usage of mineral and synthetic oils in sliding bearings of hydropower plants raises concerns about the environmental impact of these lubricants in case of spillage into downstream water. READ MORE
