  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

  2. 2. Effect of the ICRH Antenna Position on the Coupled Power in ITER and JET

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Olle Sundberg; Vincent Forsberg; [2023]
    Keywords : ;

    Abstract : Fusion energy has fascinated scientists for decades. One reason we do not see thispromising energy source powering today's society is the fact that the process requires extremeplasma temperatures. READ MORE

  3. 3. Localisation of Traumatic Brain Injury

    University essay from KTH/Medicinteknik och hälsosystem

    Author : Yogesh Sharma; MIchael Zewde Hägglund; [2023]
    Keywords : Traumatic Brain Injury TBI ; Rat brain; Finite Element Method FEM ; strain; localisation; thalamus; hypothalamus; neocortex; Traumatisk hjärnskada TBI ; Råtthjärna; Finita Element Metod FEM ; belastning; lokalisering; thalamus; hypotalamus; neocortex;

    Abstract : TBI stands for Traumatic Brain Injury and refers to damage to the brain resulting from an external physical force, such as a blow, jolt, or penetrating injury to the head. Common causes of TBI include falls, motor vehicle accidents, sports injuries, and violence and has been linked to thousands of deaths and injuries in the US and the EU alike. READ MORE

  4. 4. Modeling of a ball contact with a coated plate

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

    Author : Mohammadreza Saeedi; [2023]
    Keywords : Pin on disc tribometer; coating; contact mechanics; finite element method; tribology; Pin on disc tribometer; beläggning; kontaktmekanik; finita elementmetod; tribologi;

    Abstract : During tightening of a screw, the variation in friction will affect the force acting on the joint, especially when tightening using torque as a control parameter. So, it is crucial to have a proper understanding of the contact mechanism and friction in the screw head to joint and thread interfaces. READ MORE

  5. 5. An Arbitrary Lagrangian-Eulerian Finite Element Method for Shock Wave Propagation: Validating Simulations of Underwater Explosions

    University essay from KTH/Numerisk analys, NA

    Author : Sebastian Sandström; [2021]
    Keywords : finite element; applied mathematics; computational mathematics; hydrocode; arbitrary lagrangian-eulerian; LS-DYNA; tillämpad matematik; beräkningsteknik; finita elementmetoden; hydrokod; arbitrary lagrangian-eulerian; LS-DYNA;

    Abstract : Underwater explosions are often modeled with Arbitrary Lagrangian-Eulerian (ALE) Finite Element Methods. The objective of this thesis is to validate the simulation method, with respect to the propagating shock wave. A two-dimensional axisymmetric model of a spherical TNT charge submerged in water is simulated using LS-DYNA. READ MORE
