  1. 16. 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

  3. 17. Topology optimization : A comparison between the SIMP and BESO methods using open-source software.

    University essay from Uppsala universitet/Tillämpad mekanik

    Author : Christian Hagnell; Kiavosh Saidi Mosanen; [2021]
    Keywords : Strukturoptimering; Solid Isotropic Material with Penalization; SIMP; Bidirectional Evolutionary Structural Optimization; BESO; statiskt obestämd balk; 3D utskrift; bärande balk; öppen källkod; FreeCAD; Python;

    Abstract : Structural optimization is a useful tool for engineers and designers in construction technology as well asvehicle and mechanical engineering. With structure optimization, a computer can, with the help of finiteelement analysis, calculate the smallest possible amount of material needed to meet the requirements onthe part to be produced.

  4. 18. Micro-architectured materials for noise and vibration control in high voltage products – design and modelling

    University essay from Uppsala universitet/Tillämpad mekanik

    Author : Alec Chamberlain; [2021]
    Keywords : Microarchitectured; lattice; elasticity; viscoelasticity; computational; homogenization;

    Abstract : Many Hitachi ABB Power Grids (HAPG) products vibrate and emit noise, but legal limitations of these parameters fuel the development of energy absorption methods used on products. Methods such as Constrained Layer Damping (CLD). READ MORE

  5. 19. Improved Release Mechanisms for Aerospace Applications

    University essay from Uppsala universitet/Tillämpad mekanik

    Author : Baran Hamad; Markus Englund; [2021]
    Keywords : release mechanisms; hdrm; split spool initiator; reusable; smart materials; shape memory alloy; sma; pyrotechnic; non-explosive; spacecraft; nitinol; releasemekanismer; hdrm; fästelement; split spool-initierare; återanvändbar; minnesmetall; pyrotekniska; icke-explosiva; rymdfarkost; nitinol;

    Abstract : Hold down release mechanisms (HDRMs) are used for tightly attaching segments of bodies together when it is desired to release them rapidly at some point. When transporting sensitive payloads on launch vehicles, the challenge arises of releasing the fastened segments of the spacecraft without risking damage to the costly equipment. READ MORE

  6. 20. Energy-efficient Industrial processes : An investigation in the power consumption, power number, thrust force and torque requirement on a rotating bed reactor

    University essay from Umeå universitet/Institutionen för tillämpad fysik och elektronik

    Author : Kasim Ali Haji; [2021]
    Keywords : RBR Simulation; CFD models of an RBR; Energy-efficient Industrial processes; Power number; Power consumption; RBR; rotating bed reactor; Experimental and simulation of an RBR; Empirical models of an RBR; Thrust force; Torque requirement; k-epsilon model of an RBR; SST k-omega model of an RBR.;

    Abstract : Rotating bed reactors are used throughout the process industry. They are usedboth in the chemical industry and other industrial sectors, such as pharmaceuticals and the textile industry in decolorization due to by-products or contaminants.SpinChem AB manufactures rotary bed reactors (RBRs) to perform chemical reactions between liquids and solids.
