  1. 1. Alternative traction system for road-rail vehicles

    Master-uppsats, Lunds universitet/Innovation

    Författare :Jakob Runevad; [2023]
    Nyckelord :Product development; electric traction; construction equipment; road-rail vehicles.; Technology and Engineering;

    Sammanfattning : Excavators have traditionally been diesel driven with hydraulic actuators, but with the ongoing electrification of vehicles, smaller electric excavators are getting more common. Larger electrical excavators are still in a prototyping or early production stage but can be expected to grow. LÄS MER

  3. 2. Beräkningsmodell för oljekylare

    Uppsats för yrkesexamina på grundnivå, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Författare :Lisa Nordling; [2022]
    Nyckelord :Oljekylare; hydraulik; värmeutveckling;

    Sammanfattning : In this thesis, a calculation model for oil coolers has been worked on for Ursviken Technology AB press brakes Optima and Optiflex. Analysis of the theory behind physical phenomena has shown that a series of factors in a hydraulic system give rise to heat increase of hydraulic oil. LÄS MER

    Sammanfattning : The growing concern with the environmental impacts of disposable products has placed an emphasis on ensuring the sustainability of material systems. A shift in the selection of material can decrease the negative effects of disposable products. LÄS MER

  5. 4. Vidareutveckling av ett dämpat slagstäd till en slagutmattningsutrustning

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

    Författare :Simon Lundh; [2021]
    Nyckelord :Examensarbete; Maskinteknik; Hydraulik; Dämpning;

    Sammanfattning : Impact fatigue is an area which very little research has been carried out in. Of interest from companies in the rock drilling industry, Karlstads University has resumed research in the field of impact fatigue. During its experiments, Karlstads University wants to preform experiments with both a solid anvil and a damped anvil. LÄS MER

  7. 5. Electrically powered manoeuvring of water jets

    Uppsats för yrkesexamina på grundnivå, Uppsala universitet/Industriell teknik

    Författare :Joel Engström; [2021]
    Nyckelord :Bachelor thesis; Thesis; Mechanical engineering; Uppsala University; Design; Product development; Marine Propulsion; Electrical Actuator; Water Jets; Water Jet Propulsion; Water Jet Manouvering; Steer-by-wire; Marine Technology; Examensarbete; Maskinteknik; Kandidatuppsats; Uppsala Universitet; Konstruktion; Design; Produktutveckling; Vattenjet; vattenjetaggregat; Elektrisk Manövrering; Steer-by-wire; Marinteknik;

    Sammanfattning : A shift towards electric and hybrid propulsion within the marine sector create new challenges for conventional water jet units manoeuvred by hydraulic systems. The high efficiency in high speed water jet crafts benefit from being powered by electricity but will be compromised by constantly running hydraulic pumps, draining available electric capacity on-board.
