  1. 1. Pantograph-catenary wear modelling using dynamic simulation

    Master-uppsats, KTH/Väg- och spårfordon samt konceptuell fordonsdesign

    Författare :Gaston Holmström; [2022]
    Nyckelord :Wear modelling; catenary pantograph interaction; mechanism; conditional; railway; slitagemodellering; kontaktledning pantograf interaktion; mekanism; konditionell; järnväg;

    Sammanfattning : Wear condition modelling is a research topic which lately has increased in popularitydue to its significance to the railway industry. Large sums are spent on maintenanceof the network every year, which has generated a demand for understanding and predictingwear mechanisms in a multitude of components within both railway vehiclesand infrastructure.

  3. 2. Analys av pantograf WBL 88

    Kandidat-uppsats, KTH/Maskinkonstruktion (Inst.)

    Författare :Vincent Castellano; Albin Einarsson; Petter Norder; [2013]
    Nyckelord :;

    Sammanfattning : På uppdrag av Järnvägsgruppen på KTH skulle interaktionen mellan kontaktledning och pantograf simuleras och analyseras. Detta för att kunna presentera ett förbättrat konstruktionsförslag på pantografen som skulle leda till en jämnare kontaktkraft vid höghastighetsdrift, 300 km/h. LÄS MER

  4. 3. Active Control of the Pantograph-Catenary Interaction in a Finite Element Model

    Master-uppsats, KTH/Järnvägsteknik

    Författare :Raphael Schär; [2013]
    Nyckelord :;

    Sammanfattning : This work analyzes the implementation of an active train pantograph in a full finite element model in the program Ansys. As controller design method, the H∞ method was taken in order to cope with the different uncertainties in the given system. The focus lies on the contact force between the pantograph and the catenary. LÄS MER

  5. 4. Innovative active control strategies for pantograph catenary interaction

    Master-uppsats, KTH/Fordonsdynamik

    Författare :Roberto Tieri; [2012]
    Nyckelord :Active control; pantograph catenary interaction; actuator;

    Sammanfattning : The pantograph - catenary interaction is one of the most important features in high speed trains, and to guarantee a reliable current collection is the target that every railway system must take into consideration in order to speed up trains. The problem that goes against this direction is mainly the variation of the overhead equipment's stiness. LÄS MER
