  1. 1. 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

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

    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

  4. 3. 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

  5. 4. Self-locking Brake used in Reversible Sailboat Winches : Development of a self-locking braking system that will be used to allow sailboat winches to reverse

    University essay from Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

    Author : Lukas Andersson; [2022]
    Keywords : Sailing; Sailboat; Sailboat Winch; Reversible Winch; Winch Brake; Brake; Disk Brake; Cone Brake; Wet Brake; Brake Calculation; Seldén; Seldén Mast; One Way Clutch; One Way Bearing; Over running Roller Clutch; Electric Winch; Electric Sailboat Winch; E40i; Self Locking Brake;

    Abstract : Sailboat winches are used to help sailors manipulate the control lines that control the position and shape of the sails. Unlike most winches sailboat winches usually only have the ability to winch in the rope, but not to reverse. To reverse the line a sailor needs to manually manipulate it, this is both inconvenient and can also be a safety hazard. READ MORE

  6. 5. Piezoelectric power harvesting from mechanical strain

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

    Author : Edin Spahic; [2021]
    Keywords : piezoelectricity; roller bearing; strain; power harvesting;

    Abstract : Piezoelectric power harvesting is a field of active research. Most piezoelectric power harvesters are designed around harvesting energy from vibrations. READ MORE
