  1. 1. Agile robotic arm for vertical applications - Evaluation, design and development

    Master-uppsats, Lunds universitet/Maskinelement

    Författare :Rasmus Gren; [2023]
    Nyckelord :Robotic arm development; HKM; Kinematics; Product development; Technology and Engineering;

    Sammanfattning : Existing pick and place robots are either heavy or have a limited workspace for vertical operations. Since there is no robot today that are both light and have a good vertical workspace, this leads to a gap in the market. LÄS MER

    Sammanfattning : This Master's thesis is part of the Hydrogen Embrittlement in Rolling element bearings project (HERo) initiated at Luleå University of Technology (LTU), with the primary objective of determining critical hydrogen concentrations in bearing steel for rolling element bearings. The specific aim of this Master's thesis is to design a test rig that enables the investigation of the effects of hydrogen embrittlement on rolling element bearings under load. LÄS MER

  4. 3. Hinder för psykosociala insatser inom cancervården : En kunskapsöversikt

    Kandidat-uppsats, Marie Cederschiöld högskola/Institutionen för socialvetenskap

    Författare :Clara Mulugeta; [2022]
    Nyckelord :Psychosocial work care; Oncology Cancer; Barriers; Psykosocialt arbete vård; Onkologi Cancer; Hinder;

    Sammanfattning : The aim of this study was to scrutinize the existing barriers within psychosocial cancer care, through the cancer centers point of view. A literature review was conducted, resulting in ten peer-reviewed articles, to further investigate the psychosocial cancer care in the Western part of the world by assessing existing barriers to effective psychosocial work, and improvements needed for cancer centers to be able to offer aqequate care to patients and their loved ones.

  5. 4. Multibody modelling of the vibrations in an aircraft engine

    Master-uppsats, KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanik

    Författare :Charly Mollet; [2022]
    Nyckelord :Vibrations; Multibody Modelling; Rolling Bearings; Rotor Dynamics; Reduction Processes; Vibrationer; multikroppsmodellering; rullingslager; rotordynamik; reducktionsprocesser;

    Sammanfattning : During the assembly of aircraft engines, some clearance is left in the rolling bearings mainly to reduce friction. However this clearance might allow the rolling element to vibrate during flight. Indeed, unwanted vibrations called non-synchronous vibrations (NSV) appear on the data recorded by the sensors on some development engines. LÄS MER

  7. 5. Maskinstyrning i vält och vilken påverkan det har för lönsamhet och kvalitet.

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Författare :Oscar Brännström; Olle Rova; [2022]
    Nyckelord :lönsamhet; maskinstyrning; CMV; packningsarbete;

    Sammanfattning : Machine control for a roller is a tool that can be applied by contractors during compactionwork. The machine control includes a function that can sense how packed a surface the rollerpasses is, the degree of compaction is then reported in a dimensionless Compaction MeterValue (CMV) number.
