    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

  5. 4. Reliability-Based Sensitivity Analysis of the Dynamic Response of Railway Bridges

    Master-uppsats, KTH/Bro- och stålbyggnad

    Författare :Hasan Al-Zubaidi; [2022]
    Nyckelord :Railway bridges; High-speed trains; Simply supported beam; Global sensitivity analysis; Uncertainty quantification; Reliability; Ballast instability; Running safety; Passenger comfort;

    Sammanfattning : In response to the planned increase in operational speeds and axle loads of passengertrains that may lead to resonance-induced excessive vibrations in railway bridges,recent studies examined the reliability of bridges concerning train running safety andpassenger comfort limit states. In this respect, valuable information regarding theimportance of input variables can be obtained by conducting Sensitivity Analysis (SA). LÄS MER

  7. 5. Rail-air transport competition : A discrete choice analysis along with an international empirical investigation

    Master-uppsats, KTH/Transportplanering

    Författare :Evgeny Nikolaev; [2022]
    Nyckelord :;

    Sammanfattning : There is an increasing interest among many nations to decrease CO2 emissions.Promoting more sustainable modes of transportation is one particular area that has roomfor improvement. For instance, short and medium distance flights can bepotentially substituted by high-speed rail (HSR). LÄS MER
