  1. 16. A pre-study for functional coatings evaluated on light metals to be applied on a new HPDC Mg-alloy : Investigating tribological and thermophysical properties, as-cast and coated

    Master-uppsats, Jönköping University/JTH, Industriell produktutveckling, produktion och design

    Författare :Louise Albo Zieme; Pontus Bergstedt; [2021]
    Nyckelord :reciprocating dry sliding wear test; thermophysical test; NiP-SiC; Ni-SiC; functional coatings; progressive scratch test; adhesion; magnesium alloy; aluminium alloy; hardness.;

    Sammanfattning : Magnesium with two-thirds of the density compared to aluminium and one-quarter of steel, intrigues product developers and material scientists due to the light metal’s excellent combination of strength to weight ratio as well as their capability of being produced as a High Pressure Die Cast component compared to other ferrous or light metal alloys.   However, a magnesium alloy inherits some concerning drawbacks, limiting the exploitation in structural applications and mechanical design such as automotive, heavy machinery and aerospace components.

  4. 18. 2D Modelling of Geosynthetically Reinforced Piled Embankments : Calibration Methods in PLAXIS 2D & Review of Analytical Guidelines

    Master-uppsats, KTH/Jord- och bergmekanik

    Författare :Maya Sleiman; [2021]
    Nyckelord :;

    Sammanfattning : This thesis focuses on the 2D modelling of Geosyntheticaly Reinforced Piled Embankments (GRPE) in PLAXIS 2D. In doing so, it explores two main aspects: 1) the calibration of Interface Stiffness Factors (ISFs) governing the soil-pile interaction of Embedded BeamRow (EBR) elements in PLAXIS 2D, and 2) the prospects and limitations of modelling geogrids (GR) in PLAXIS 2D when underlain by EBR elements; although several studies have validates the EBR element in modelling piles, none address the geogrid-EBR interaction and its implications on modelling GRPE systems.

  5. 19. Dimensioning of a cutter wheel bearings

    Master-uppsats, Karlstads universitet/Institutionen för ingenjörsvetenskap och fysik (from 2013)

    Författare :Kebin Xie; [2020]
    Nyckelord :cutter wheel; bearing; wear; scuffing; Archard equation; lubrication number; Reynold equation; Hertzian contact theory; impact load factor; FE model; Ansys; contact pressure on bearing;

    Sammanfattning : Mobile Miner 40V is a machine used for rock excavation and developed by Epiroc. This machine is equipped with a large cutter wheel to perform the excavation. After a test run, some surfaces associated with bearings within the cutter wheel were found to be damaged due to scuffing - severe sliding wear. LÄS MER

  7. 20. Development of a method for estimation of contact fatigue life in hypoid gears

    Master-uppsats, KTH/Maskinkonstruktion (Inst.)

    Författare :Srigiripura Sahana Vittal; [2020]
    Nyckelord :Hypoid Gear; Rolling Contact fatigue; Fatigue life; FEM; Gear Contact life; Spalling; physical testing; fatigue analysis; Hypoidväxel; rullande kontaktutmattning; utmattningslivslängd; FEM; växelkontaktlivslängd; spalling; fysisk testning; utmattningsanalys;

    Sammanfattning : Hypoid gears have been used extensively in automobiles, aerospace, marine and other applications for decades. The special advantages of hypoid gears come with inherent contact complexities of varying curvature and sliding in both profile and lengthwise direction. LÄS MER
