  1. 26. Thermo-mechanical fatigue of castiron for engine applications

    University essay from KTH/Maskinkonstruktion (Inst.)

    Author : Niklas Collin; [2014]
    Keywords : Thermo-mechanical fatigue; TMF; CGI; LGI; fatigue; thermal strain; Termomekanisk utmattning; TMF; CGI; LGI; termisk töjning;

    Abstract : In an engine component the repeated start-stop cycles cause temporal and local inhomogeneous temperatures, which in turn lead to a type of low-frequency loading, plastic deformation and eventually failure due to thermo-mechanical fatigue. Simultaneously, high-frequency mechanical loading arises from the cyclic combustion pressure and from road induced vibrations. READ MORE

  3. 27. Analysis of fan blade attachment

    University essay from Högskolan i Skövde/Institutionen för ingenjörsvetenskap

    Author : Patrick Shingu; Miguel Garcia Cabrera; [2014]
    Keywords : Axial Fan; Paremetric Study; Finite Element Analysis; Fatigue; Modal Analysis;

    Abstract : This thesis work is based on the analysis of a fan blade attachment whereby a complete 3D model is presented by a partner company. The acceptability of a new design regarding the mechanical loads consisting of dividing the hub into two parts instead of using a solid hub is studied. READ MORE

  4. 28. The effectiveness of grouted macadam at intersections. : A life-cycle cost analysis

    University essay from KTH/Väg- och banteknik

    Author : Sofie Jacobsen; [2012]
    Keywords : grouted macadam; life-cycle cost analysis; LCC; rutting; intersections.;

    Abstract : Intersections often experience severe rutting in the asphalt concrete layers due to slow moving, high loads, acceleration, deceleration and turning. This thesis aims to investigate the effectiveness of grouted macadam, open graded asphalt with its voids filled with cement grout, as a pavement material at intersections. READ MORE

  5. 29. High cycle fatigue properties of stainless martensitic chromium steel springs

    University essay from KTH/Materialteknologi

    Author : Pouyan Pirouznia; [2012]
    Keywords : High cycle fatigue; Local stress; Nominal stress; FEM modeling; SEM; EDS;

    Abstract : For many materials and components like in high speed trains and airplanes fatigue failures occur in the range of over 107 load cycles which is called the high cycle fatigue range. A modern version of the springs was invented which are applied in a certain application. READ MORE

  6. 30. Redesign of Steam Strainer

    University essay from Institutionen för ekonomisk och industriell utveckling

    Author : Ann Jannesson; [2008]
    Keywords : Steam strainer; Steam turbine; Concept development; Material choice; Manufacturing process selection;

    Abstract : This thesis was done at Siemens Industrial Turbomachinery AB in Finspång. Placed in the inlet to a steam turbine is a filter, a steam strainer, which separates particles and larger objects from the steam. These particles and objects will cause solid particle erosion in the actual turbine if they pass by. READ MORE
