  1. 1. Estimating the load weight of freight trains using machine learning

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

    Författare :Erik Kongpachith; [2023]
    Nyckelord :Railway freight Transport; Rail Vehicle Weighing; Y25 Bogie; Sdggmrss T3000eD; GENSYS; Machine Learning; Regression; Polynomial Regression; Regression Trees; Random Forest Regression; Support Vector Regression; Järnvägsgods transport; Vägning av järnvägsfordon; Y25 Bogie; Sdggmrss T3000eD; GENSYS; Maskininlärning; Regression; Polynom Regression; Regressionsträd; Random Forest Regression; Support Vector Regression;

    Sammanfattning : Accurate estimation of the load weight of freight trains is crucial for ensuring safe, efficient and sustainable rail freight transports. Traditional methods for estimating load weight often suffer from limitations in accuracy and efficiency. LÄS MER

  3. 2. Investigation of sources of wheel-rail impact force deviation through dynamic simulations

    Master-uppsats, KTH/Fordonsdynamik

    Författare :Sumanth Ram Aravindababu; [2021]
    Nyckelord :Multi-body simulations; wheel damages; rail damage; damage thresholds; wheel-rail impact forces; classification; Flerkroppssimulering; hjulskador; rälskador; skadetrösklar; hjulslagkraft; rälslagkraft; klassificering;

    Sammanfattning : Due to the increase in demand on freight transportation it becomes necessary to avoid delays to ensure that the goods reach its destination on time. The main factors causing disturbances in the traffic on the mainline is the breakdown of vehicles mainly due to damaged wheels. LÄS MER

  4. 3. System-wide LCC Calculation for Novel Brake Block Material in Nordic Condition

    Master-uppsats, KTH/MWL Marcus Wallenberg Laboratoriet

    Författare :Alfi Hadi Firdaus; [2018]
    Nyckelord :;

    Sammanfattning : One of the main issues of cast-iron block brake material is high noise. Nowadays, train operators tend to change the brake block material from cast-iron to composite material. However, composite block brake materials are likely to produce more wear than cast-iron block brakes, degrading the dynamic behavior of the vehicle on the track. LÄS MER

  5. 4. Investigation of Causes for Wheel Squeal on Roslagsbanan in Stockholm

    Master-uppsats, KTH/Spårfordon

    Författare :Zhan Ouyang; [2014]
    Nyckelord :;

    Sammanfattning : The purpose of this work is to investigate the possible causes of wheel squeal on Roslagsbanan, a narrow gauge (891mm) suburban railway system in Stockholm, Sweden. Simulation of the dynamic behaviour of vehicles negotiating curves was carried out by means of the Swedish multibody simulation software GENSYS [1]. LÄS MER

  7. 5. Running Dynamics for a Maintenance Railway Vehicle

    Master-uppsats, KTH/Järnvägsteknik

    Författare :Michael Gustafsson; [2014]
    Nyckelord :;

    Sammanfattning : BS Verkstäder has developed a new railway maintenance vehicle, MTR2000, which is in the process of authority approval. A part of the approval is the running dynamics of the vehicle which for maintenance vehicles following SS‐EN 14033‐1 can be evaluated using a simulation model of the vehicle, which is verified by comparing simulation results to measurements from a vehicle test.
