  1. 1. Enabling More Efficient E-Mobility : Grease Development by a Novel Bearing-Grease Test Machine

    University essay from KTH/Maskinkonstruktion (Avd.)

    Author : Gabriel Benjamin Calderon Salmeron; [2019]
    Keywords : Deep groove ball bearing; Lithium complex grease; Polypropylene grease; energysaving potential; High speed bearing-grease testing machine; Spårkullager; Litiumkomplexfett; Polypropenfett; Energibesparingspotential; Höghastighetslagermaskin;

    Abstract : The inclusion of electric vehicles in the automotive industry represents an opportunity for lubricating grease producers. Different speed, loads, and electric conditions are present in the bearings of the electric vehicles when compared with the conditions in a traditional internal combustion engine vehicle. READ MORE

  2. 2. The rotation of a stored cylinder body by an outer rotating structure.

    University essay from Luleå tekniska universitet/Rymdteknik

    Author : Christopher Vestman; [2019]
    Keywords : Cylinder; Rotation; HEAT; Shaped Charge; Gessner;

    Abstract : HEAT-grenades are wing-stabilized grenades using shaped charge technology. Theshaped charge is a method, producing a jet-beam, with the use of a copper linerin which the aim is to focus the detonation energy to be able to penetrate armourand structures. READ MORE

  3. 3. Hertz contact influence on acoustic emission signals originating in radial bearings : Test rig construction and experimental evaluation

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

    Author : Joel Klippås; [2018]
    Keywords : Hertz contact; Acoustic emission; Radial bearings;

    Abstract : During the project a test rig was constructed in which experiments were performed on radial bearings to evaluate the acoustic emission amplitude and RMS value of the signal. The acoustic emission amplitude depends on the Hertz contact time, i.e. the time it takes for the Hertz contact to roll over its own contact length. READ MORE

  4. 4. Ball Bearing Design Tool Evaluation​

    University essay from KTH/Rymdteknik

    Author : Simon Rommelaere; [2017]
    Keywords : ;

    Abstract : This report has been written during my internship/master thesis at Thales Alenia Space, Cannes, FRANCE. The subject of the thesis is ball bearing design, and is focused on the software RBSDyn. This software has been developed by CNES, the French Center for Space Studies, and is used to simulate bearings behaviors under various conditions. READ MORE

  5. 5. Optimisation of ceiling attachment for AVPOS using FEA

    University essay from Högskolan i Skövde/Högskolan i Skövde/Institutionen för teknik och samhälleInstitutionen för ingenjörsvetenskap

    Author : Mikael Koskenranta; [2015]
    Keywords : optimisation; topology optimisation; ceiling attachment; AVPOS; redesign; FEA; finite element analysis; DFMA; design for manufacture and assembly; DFA; design for assembly; DFM; design for manufacture;

    Abstract : In product manufacture and assembly it is important to lower materials usage and assembly timewhile retaining a safety margin against structural failure. In this project the ceiling attachment of theAVPOS offloading arm is redesigned based on objectives identified by Löfs Specialmaskiner. READ MORE
