  1. 1. High Temperature Tribology of Aluminium : Effect of Lubrication and Surface Engineering on Friction and Material Transfer

    Författare :Justine Decrozant-Triquenaux; Jens Hardell; Manel Rodriguez Ripoll; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Machine Elements; Maskinelement;

    Sammanfattning : Lightweight design for automotive applications has been pursued for several decades and continues to increase. The main driving forces are new and increasingly stringent emission regulations as well as the increasing popularity of electric, or hybrid, vehicles where the increased weight of the batteries need to be compensated by light weight structures.

  4. 3. Electrical Characterisations of Bearings

    Författare :Abhishek Joshi; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Ball bearing; Equivalent circuit model; Lubricants; Bearing Capacitance; Spherical bearing; Mechanical bearing; Bearing currents; Electrical conduction; Electrical characterisation;

    Sammanfattning : Mechanical bearings are an integral part of industry, and are used in various places in order to reduce friction between two interacting surfaces and are used to transmit power and loads. Mechanical bearings are one of the most extensively used components within the wind industry, but on the other hand they are also one of the most dominantly failing failed components. LÄS MER

  5. 4. Lubrication mechanisms and properties of non-halogenated orthoborate ionic liquids

    Författare :Patrick Rohlmann; Sergei Glavatskih; Mark W. Rutland; Oleg N Antzutkin; Ali Erdemir; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Ionic Liquids; Friction; Wear; Viscosity; Density; Additive; Machine Design; Maskinkonstruktion;

    Sammanfattning : One way to reduce energy consumption and waste - a necessity to achieve the UN-mandated limitation of average global temperature in-creases - is to select suitable lubricants so that energy-losses through friction and wear are minimised. In this context, non-halogenated ionicliquids (ILs) are promising candidates to achieve this aim due to their intrinsic ionic properties, low vapour pressure and high thermal stability. LÄS MER

  7. 5. Active friction control by using CO2 and moisture

    Författare :Jing Hua; Shi Yijun; Shah Faiz; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; friction control; Machine Elements; Maskinelement;

    Sammanfattning : Nowadays the demand for intelligent control of tribological interactions is strongly increasing in various applications. We often strive to minimize friction but there are also many situations where high friction is desirable. In some cases, something in between, i.e. LÄS MER
