  1. 1. Micromechanical modelling of creep in wooden materials

    University essay from Uppsala universitet/Tillämpad mekanik; Uppsala universitet/Tillämpad mekanik; Uppsala universitet/Tillämpad mekanik

    Author : Oskar Falkeström; Kevin Coleman; Malin Nilsson; [2021]
    Keywords : Creep; RVE; Homogenization; Honeycomb; Tracheid; Comsol Multiphysics; Micromechanical modelling; Orthotropic; Parametric study; S2 material; Norwegian Spruce; Scots Pine; Cell geometry;

    Abstract : Wood is a complex organic orthotropic viscoelastic material with acellular structure. When stressed, wood will deform over timethrough a process called creep. Creep affects all wooden structureand can be difficult, time-consuming and expensive to measure. For this thesis, a simple computer model of the woodenmicrostructure was developed. READ MORE

  2. 2. Structural Investigations of Novel Heliostat Designs based upon the Hydraulic Infinite Linear  Actuator (HILA)

    University essay from Linköpings universitet/Mekanik och hållfasthetslära

    Author : Venkata Nikhil Nandigama; [2021]
    Keywords : Structural Analysis; Heliostat; Mechanics; Topology optimization; Finite element methods; concentrated solar power; renewable energy.;

    Abstract : A heliostat is a device that reflects the sun’s rays to a stationary object. There are two different types of heliostat serial and parallel type. The most used is the serial type of heliostat with Azimuthal-Elevation(Az-El) drive. READ MORE

  3. 3. Identifying Important Features to Minimize Hole Deviation in Percussive Drilling

    University essay from KTH/Maskinkonstruktion (Inst.)

    Author : Ketan Dhananjay Deshpande; [2021]
    Keywords : Bending; Buckled profile; Drilling; Hole deviation; Mathematical model; Böjning; Buckled profil; Borrning; Hålavvikelse; Matematisk modell;

    Abstract : Hole deviation is one of the most significant problems in drilling applications. Deviated holes result in inefficient blasting and have severe economic impacts due to increased equipment consumption. Conversely, straighter holes help in increasing production scales and reduce operational costs. READ MORE

  4. 4. Investigating the process parameters that influence the z-strength of liquid paperboard using data mining and machine learning

    University essay from Uppsala universitet/Tillämpad mekanik

    Author : Gustav Thaung Tolförs; [2021]
    Keywords : paperboard; liquid paperboard; z-strength; process parameters; machine learning; data mining;

    Abstract : Parameters affecting the z-strength of liquid paperboard (LPB) has been analyzed and identifiedusing data mining and machine learning on 6 years of operational data from a multi-ply LPB mill, and control and stabilizing of them was proposed. Linear regression models were built for 9 articles with satisfactory results, and whose attributes were further analyzed as the most important parameters for the z-strength. READ MORE

  5. 5. Design and Evaluation of a Novel Conveyor Utilizing a Screw Mechanism to Move Objects With Integrated Racks

    University essay from KTH/Mekatronik; KTH/Mekatronik

    Author : Måns Nilsson; Mathias Nils Edvin Nordqvist; [2021]
    Keywords : Screw Conveyor; Intralogistics; Material Handling; Thread Meshing; Worm rack drive; Brushless motor; Skruvtransportör; Intralogistik; Materialhantering; gängingrepp; Snäckskruv och kuggstång; borstlös motor;

    Abstract : Intralogistics, or material handling, traditionally use roller or chain conveyors to moveo bjects and goods in factories and warehouses. One negative aspect of the traditional types of conveyors is that they are expensive, as they are comprised of many moving parts. READ MORE
