  1. 1. The OpenXO. 3D Printed Modular Exoskeleton Segment

    University essay from Luleå tekniska universitet/Rymdteknik

    Author : Árni Þór Þorgerirsson; [2023]
    Keywords : Exoskeleton; Open-Source; Fused Filament Fabrication FFF ; Cycloidal Drive; OpenXO; precision fabrication;

    Abstract : Exoskeletons are wearable devices that enhance or supplement the user’s natural abilities. They have been demonstrated to be efective in alleviating pain, reducing work related injuries, improving working conditions, and can play a pivotal role in improving recovery times and recovery outcomes.

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

    University essay from Lunds universitet/Maskinelement

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

    Abstract : 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. READ MORE

  4. 3. Design of a test rig for in situ hydrogen charging of rolling element bearings under load

    University essay from Luleå tekniska universitet/Maskinelement

    Author : Oskar Moström; [2023]
    Keywords : tribology; hydrogen embrittlement; mechanical engineering; rolling element bearing; machine elements; design; mechanical design; CAD; mechanical construction; construction; material science; Tribologie; Wasserstoffversprödung; Maschinenbau; Wälzlager; Maschinenelemente; Design; Maschinenkonstruktion; CAD; mechanischer Bau; Konstruktion; Materialwissenschaft; tribologi; väteförsprödning; maskinteknik; rullningselementlager; maskinelement; design; mekanisk design; CAD; mekanisk konstruktion; konstruktion; materialvetenskap; lager;

    Abstract : 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. READ MORE

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

    University essay from KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanik

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

    Abstract : 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. READ MORE

  6. 5. Fault diagnosis of axlebox roller bearings of high speed rail vehicles based on empirical mode decomposition and machine learning

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : JOSUA KEHLENBACH; [2021]
    Keywords : Condition monitoring; axlebox bearings; machine learning; data fusion; Nyckelord: tillståndsövervakning; axelboxlager; maskininlärning; datafusion;

    Abstract : Axlebox bearings are one of the most critical components of a rail vehicle with regard to safety. An axlebox bearing that breaks during operation can be dangerous for the passengers and expensive for the operator. In-service failure of axlebox bearings has been the cause of many catastrophic accidents. READ MORE
