  1. 1. Machine Learning on Terrain Data and Logged Vehicle Data to Gain Insights into Operating Conditions for an Articulated Hauler : Machine Learning on Terrain Data and Logged Vehicle Data to Gain Insights into Operating Conditions for an Articulated Hauler

    University essay from Uppsala universitet/Institutionen för informationsteknologi

    Author : Tianren Sun; Yen Chieh Wang; [2022]
    Keywords : CNN; Data Driven Manufacturing; Microsoft Azure Maps; Machine; Learning ML ; Road Surface; Topography;

    Abstract : Manufacturers can develop next-generation production and service for their customers by the data gathered and analyzed from customers’ usage conditions. In this research, the operating condition of articular haulers is collected and analyzed through machine learning algorithms to predict the type of operational topographies and road surface.

  3. 2. Development of a method for estimation of contact fatigue life in hypoid gears

    University essay from KTH/Maskinkonstruktion (Inst.)

    Author : Srigiripura Sahana Vittal; [2020]
    Keywords : 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;

    Abstract : 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. READ MORE

  4. 3. Material Transfer Mechanisms during Interaction of Aluminium Alloy and Tool Steel at Elevated Temperatures

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Gabriel Macêdo; [2020]
    Keywords : material transfer mechanisms; high temperature tribology; hot metal forming tribology; hot-stamping of aluminium alloys; aluminium alloys;

    Abstract : Hot stamping of aluminium alloys allows for increased formability, decreased springback and the possibility of integrating age-hardening heat treatments into the process. However, it can be challenging due to the occurrence of material transfer of aluminium onto the tool, as aluminium is prone to adhesion even at low temperatures. READ MORE

  5. 4. Simulation of Tribological Contacts in Hydraulic Machines

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Fredrik Roselin; [2018]
    Keywords : Tribology; Friction; Wear; Lubrication; Mixed lubrication; Luleå Mixed Lubrication Model; LMLM; Tribologi; Friktion; Nötning; Smörjning; Blandad tunnfilmssmörjning;

    Abstract : Axial piston machines are operating at high pressure and varying speeds, which requires high reliability of the components. The machine components are separated by a fluid film, but sometimes this film gets penetrated by the surface asperities causing the machine to operate with metal-to-metal contact. READ MORE

  6. 5. Sliding bearings in heavy duty engines : A bearing wear comparative study

    University essay from KTH/Maskinkonstruktion (Inst.)

    Author : Mathias Anslin; Alexander Bölke; [2017]
    Keywords : Start-Stop; Wear; Surface topographies; Heating design; Start-Stopp; Nötning; Yttopografi; Värmekonstruktion;

    Abstract : Start-stop systems are widely used in the car industry today but have not yet been fully implemented in the heavy-duty vehicle industry. The greater loads arising in the engines leads to excessive wear of the hydrodynamic bearings during starts and stops which has a distinct impact on the machine´s lifetime performance and reliability.
