  1. 1. Co-Simulation Development for Improved Cavitation Predictions in Oil-Hydraulics Systems : An investigation into the cavitating flow behavior of repetitive water hammers.

    University essay from Linköpings universitet/Mekanisk värmeteori och strömningslära

    Author : Thisal Mandula Sugathapala; Twan Bakker; Rahul Gudur Suresh; Aryan Delir; [2022]
    Keywords : co-simulation; water hammer; cavitation;

    Abstract : Numerical modeling of cavitation using computational software is a highly pursued topic of research due to its impact in different industrial sectors. While some industrial applications such as wastewater treatment and mineral processing are known to advantageously use this phenomena, it remains an unwanted process in others where it is known to induce vibration, reduce performance and cause structural damage.

    University essay from Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

    Author : Albin Hugoh; [2019]
    Keywords : ;

    Abstract : Today the automotive industry is going through big changes and facing many new challenges due to the transformation to a sustainable transport solution in combination with tougher legal demands. Gears have been around for a long time and it is one of the most efficient ways of transferring rotary motion from one shaft to another. READ MORE

  5. 4. Non-Linear FE-Analysis of a Composite Action Girder with Coiled Spring Pins as Shear Connectors

    University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Author : Simon Stahlin; [2019]
    Keywords : composite bridge; composite action; shear connector; coiled spring pins; finite element modeling; samverkansbro; samverkan; skjuvförbindare; spiralbult; finita element modellering;

    Abstract : For bridges to cope with increased requirements such as increased loads, strengthening work can be carried out. In cases where older steel-concrete bridges do not have a composite action, an alternative is to create composite-action to achieve a higher flexural strength. It is introduced by post-installing shear connectors. READ MORE

  6. 5. Methodology and vibrational analysis for measurements on a VTOL RAPS

    University essay from Linköpings universitet/Fluida och mekatroniska system

    Author : Dino Krantz; [2017]
    Keywords : Experimental modal analysis; impact hammer test; methodology; structural vibration; RPAS; VTOL; Certification;

    Abstract : In this thesis a methodology for measuring vibrations has been produced andinvestigated for APID 60, a rotorcraft in a Vertical Take-off and landing remotelypiloted aircraft system (VTOL RPAS). A comparative study was carried out forthe purpose of identifying the methodology with respect to design modificationscommon to the APID 60. READ MORE
