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

   Master-uppsats, Linnéuniversitetet/Institutionen för maskinteknik (MT)

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

   Sammanfattning : 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. LÄS MER

3. 2. Investigation of case hardened steel subjected to torsion: An experimental and numerical elastic-plastic material study

   Master-uppsats, KTH/Hållfasthetslära

   Författare :Jonathan Fridstrand; [2022]
   Nyckelord :Torsion; Shear stress-strain relation; Elastoplastic material; Case hardened steel; Custom material model; Vridning; Skjuvtöjning och -spänning; Elastiskt-plastiskt material; Sätthärdat stål; Anpassad materialmodell;

   Sammanfattning : There is currently a knowledge gap regarding the plastic material properties of many steel types that Atlas Copco use in their high torque power tools. This makes it difficult to fully utilise the capabilities of the Finite Element Method (FEM) to aid the developmental process. LÄS MER

4. 3. Torsional Stiffness Calculation of CFRP Hybrid Chassis using Finite Element Method : Development of calculation methodology of Formula Student CFRP Chassis

   Master-uppsats, Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

   Författare :Abb Assaye; [2020]
   Nyckelord :FEA; FEM; Formula Student; FSAE; Torsion; Torsional Stiffness; Torsional Rigidity;

   Sammanfattning : Composite sandwich structures are being used in the automotive and aerospace industries at an increasing rate due to their high strength and stiffness per unit weight.  Many teams in the world’s largest engineering competition for students, Formula Student, have embraced these types of structures and are using them in their chassis with the intent of increasing the torsional stiffness per unit weight.

5. 4. Design and Construction of High Current Winding for a Transverse Flux Linear Generator Intended for Wave Power Generation

   Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Författare :Ahmed Amine Ramdani; Sebastian Rudnik; [2018]
   Nyckelord :Wave-power; transverse flux generator; winding; aluminum conductor; magnetic flux leakage; ocean energy; wave energy; wave energy generator; electromotive force; parallel strands; circulating currents; crowding effects; skin effect; proximity effect; eddy currents; racetrack effect; cable twisting; AlCu connection; enamel; polyamide-imide; dicloromethane; Vågkraft; transversalflödesgenerator; lindningsledare;

   Sammanfattning : There is currently a high demand for electric power from renewablesources. One source that remains relatively untapped is the motionof ocean waves. LÄS MER

7. 5. Development of a Shrouded SteamTurbine Flutter Test Case

   Master-uppsats, KTH/Kraft- och värmeteknologi

   Författare :Ren Jinghe; [2017]
   Nyckelord :shrouded blade; flutter; hot-to-cold; CFD; höljet; fladdret; hot-to-cold; CFD;

   Sammanfattning : A shrouded blade was designed as a test case for flutter analysis of steam turbine. Flutter is a self-excitedvibration. It can lead to dramatic blade loss and high-cycle fatigue. Shrouded blade is more complicated onflutter analysis, because the mode shapes are more complex with bending and torsion components atdifferent phases. LÄS MER
