  4. 2. Analysis of rail breaks and insulated joint deterioration

    Author : Johan Sandström; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Rail breaks; Heavy Haul; Insulated joints; Wheel flats; Railway mechanics; Material fatigue;

    Abstract : The thesis deals with fatigue related issues in the field of railway mechanics. In particular rail breaks and deterioration of insulating joints are investigated. The study is largely motivated by plans to increase allowed axle loads in Sweden. READ MORE

  5. 3. Analysis of Ball CV-joints of Fixed Type

    Author : Peter Andersson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; frictional forces; displacements; contact angles; load distribution;

    Abstract : Two theoretical models for analysing ball CV-joints of fixed type are presented. The models, which have been implemented in computer programs, calculate internal conditions such as load distribution, contact angles and displacements for different operating conditions. READ MORE

  6. 4. Mathematical modelling of jointed rock masses

    Author : Thomas Olofsson; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Construction Engineering and Management; Byggproduktion; Structural Engineering; Konstruktionsteknik;

    Abstract : In this thesis, a theoretical model of the mechanical behaviour of jointed rock masses is developed. An equivalent material approach is used to formulate the constitutive equations, where the structural components, intact rock and joints are assigned continuous material properties. READ MORE

  7. 5. Friction in threaded fasteners : Influence of materials and tooling
