  1. 1. Investigation of torsion modes in overhead traveling cranes: : Reviewing the ISO 22980 standard

    University essay from Linnéuniversitetet/Institutionen för maskinteknik (MT)

    Author : Simon Jens; [2023]
    Keywords : Overhead traveling crane; Finite element method; Frequency and experimental vibration analysis; Travers; finita elementmetod; egenfrekvensanalys; experimentell vibrationsanalys;

    Abstract : Overhead cranes and rail mountings in the wall are subjected to vibrations whenlifting equipment. The purpose of this thesis is to review if the minimum frequencyvalue for cranes, according to the ISO 22986:2007 standard is conservative whendesigning overhead traveling cranes. READ MORE

  3. 2. Modelling and testing of a solar panel structure for KNATTE (Kinesthetic Node and Autonomous Table-Top Emulator)

    University essay from Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Author : Elena Fernández Bravo; [2021]
    Keywords : Frictionless platform; Linear Quadratic Gaussian; Flexible appendages; Finite Element Method;

    Abstract : One of the challenges that satellites face is the interaction between control movement and vibration of flexible appendages such as solar arrays and antennas that can negatively affect the performance of the spacecraft. The aim of this thesis is to develop a numerical model of a solar panel structure for KNATTE, a frictionless platform developed by the Onboard Space Systems group at Luleå University of Technology, and develop a control law that reduces the flexible vibration of the solar arrays when attitude control manoeuvres are performed.

    Keywords : Electric Vehicles; Permanent Magnet Synchronous Machine; flux; flux linkage; Inductance; Model based design; Finite Element Analysis; Mechanical drivetrain; Magnetic saturation; Cross-coupling; Spatial harmonics; Temperature; Active oscillation damping; ABS wheel speed sensor; CAN bus.; Elektriska fordon; synkronmaskiner med magneter; magnetiskt flöde; induktans; modellbaserad design; Finite Element Analys; mekanisk drivlina; magnetisk mättnad; magnetisk tvärkoppling; MMF övervågor; temperatur; aktiv oscillationsdämpning; ABS hjulhastighetssensor; CAN buss.;

    Abstract : When developing three-phase drives for Electric Vehicles (EVs), it is essential to verify the controller design. This will help in understanding how fast and accurately the torque of the motor can be controlled. READ MORE

  5. 4. Numerical analysis of aerodynamic damping in a transonic compressor

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

    Author : Vincenzo Stasolla; [2019]
    Keywords : transonic compressor; flutter; vibration; CFD; transonic kompressor; fladder; vibration; CFD;

    Abstract : Aeromechanics is one of the main limitations for more efficient, lighter, cheaper and reliable turbomachines, such as steam or gas turbines, as well as compressors and fans. In fact, aircraft engines designed in the last few years feature more slender, thinner and more highly loaded blades, but this trend gives rise to increased sensitivity for vibrations induced by the fluid and result in increasing challenges regarding structural integrity of the engine.

  6. 5. Remote control of mechanical rat traps based on vibration and audio sensors

    University essay from Lunds universitet/Avdelningen för Biomedicinsk teknik

    Author : Denis Solak; Amin Storani; [2019]
    Keywords : Technology and Engineering;

    Abstract : The main aim with this master’s thesis was to study the possibilities of detecting an event (rat trap going off) by analyzing audio streams from a MEMS (micro-electromechanical systems) microphone or movement patterns from a MEMS accelerometer. To achieve this goal, a small, power efficient and cost efficient embedded system was built with the help of a development board, a MEMS accelerometer, a MEMS microphone and a metal box where the equipment and the rat traps were placed and positioned.
